Ferrous ion is oxidized to ferric ion by potassium permanganate according to the following equation :
10 FeSO4 + 2 KMnO4 + 8 H2SO4 → 5 Fe2(SO4)3 + K2SO4 + 2 MnSO4 + 8 H2O
Firs 98% sulfuric acid is added to 200 ml water in the Erlenmeyer flask and the two are mixed together.
Then potassium permanganate solution is added.
When the two are ready iron(II) sulfate solution is added to the flask causing an instantaneous change in color from the deep violet of permanganate ion to the light green - white of the iron(III) sulfate.
This reaction is much faster than other because according to the collision theory only some collision are effective depending on the form of the molecule the temperature and the concentration .
At the same concentration this reaction is much faster than other because of the nature of iron(II) ion that, being spherical, is reactive towards all oxidizing ions or molecules coming from all directions.

The precipitation of metallic iron from a solution of iron (II) sulfate http://chemistry-chemists.com/N3_2016/ChemistryAndChemists_3_2016-P9-1.html
Получение железа из водного раствора сульфата железа (II)
После эксперимента коллеги Termoyad по получению металлического цинка из водного раствора http://chemistry-chemists.com/N3_2016/ChemistryAndChemists_3_2016-P7-1.html решил провести аналогичный эксперимент с железом. Скажу сразу, задача получить железо в качестве реактива не стояла: слава богу, железа пока хватает. Стояла задача ответить на вопрос: можно ли выделить металлическое железо из водного раствора солей химическим способом? Цинк легко образует гидрокомплексы при растворении гидроксида цинка в щелочах, про железо такое не скажешь, поэтому придется обойтись кислыми растворами.
В качестве исходного вещества использовал соль Мора, FeSO4·(NH4)2SO4·6H2O двойной сульфат железа (II) и аммония. Дальше для простоты его формула будет обозначаться как FeSO4 (т.к. сульфат аммония в данном случае практически является балластом). Казалось бы, получить железо из раствора сульфата двухвалентного железа просто, достаточно добавить более активный металл, например, магний. Помните, в школе писали реакции вроде приведенной ниже:
FeSO4 + Mg = MgSO4 + Fe
Так вот, это уравнение можно смело заранее перечеркнуть. Почему?
В водном растворе сульфата железа (II) находится сразу два катиона-окислителя - Fe2+ и H+. Последний образуется в результате гидролиза. Водород расположен в электрохимическом ряду напряжений правее железа, поэтому согласно теории восстанавливаться должны, прежде всего, катионы водорода, а уже потом - катионы железа. На практике, скорее всего, эти процессы будут идти одновременно.
Если катионы водорода будут реагировать с магнием, то равновесие гидролиза сместится вправо - гидролиз приведет к образованию осадка гидроксида железа или основных солей.
Чтобы основные соли не выпадали, нужно добавить кислоту. Решил использовать лимонную кислоту, т.к. она сравнительно слабая, и если и будет реагировать с железом, которое образуется, то не слишком быстро.
Поместил кусочек магния в раствор соли Мора и лимонной кислоты. Началось выделение водорода - не очень сильное, но аэрозоль раствора летел стабильно. Зеленоватый раствор быстро стал светло-серым, со временем - темно-серым, в конце - черным (при разбавлении порции темного раствора она становилась коричневой с зеленоватым оттенком). Растворение магния продолжалось примерно 2 часа - реакция шла сравнительно медленно. Раствор заметно нагрелся.
Вскоре после начала реакции стало заметно образование мелкого порошка железа, который оседал на дно или был взвешен в растворе. Поднес к стакану магнит, образовавшийся порошок железа притянулся к магниту и собрался на стенке стакана. Кусочек магния также примагнитился, т.к. на его поверхности осело железо.

Iron (/ˈaɪərn/ EYE-ər-n) is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Iron's very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to the most common isotope of iron) is the last nuclear fusion reaction that is exothermic. This causes radioactive nickel to become the last element to be produced before collapse of a supernova leads to the explosive events that scatter this precursor radionuclide of iron abundantly into space.
Like other group 8 elements, iron exists in a wide range of oxidation states, −2 to +8, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give iron oxides, also known as rust. Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than iron metal, and thus iron oxides flake off and expose fresh surfaces for corrosion.

Iron(II) sulfate (Br.E. iron(II) sulphate) or ferrous sulfate is the chemical compound with the formula FeSO4. It is used medically to treat iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol, the blue-green heptahydrate is the most common form of this material. All iron sulfates dissolve in water to give the same aquo complex [Fe(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic. This video is targeted to blind users.

REDOX : iron(II) sulfate oxidation with permanganate ion
Ferrous ion is oxidized to ferric ion by potassium permanganate according to the following equation : 10 FeSO4 + 2 KMnO4 + 8 H2SO4 → 5 Fe2(SO4)3 + K2SO4 + 2 MnSO4 + 8 H2O Firs 98% sulfuric acid is added to 200 ml water in the Erlenmeyer flask and the two are mixed together. Then potassium permanganate solution is added. When the two are ready iron(II) sulfate solution is added to the flask causing an instantaneous change in color from the deep violet of permanganate ion to the light green - white of the iron(III) sulfate. This reaction is much faster than other because according to the collision theory only some collision are effective depending on the form of the molecule the temperature and the concentration .

Synthesis of Iron (II) Sulfide (FeS)
The synthesis of iron (II) sulfide involves reacting 1 equivalent of sulfur with 1 equivalent of iron. The reaction is initiated by a hot glass stirring rod into it. It is an extremely exothermic reaction. This is an interesting reaction to use as a demonstration, but the product is useful. The Iron (II) sulfide, or FeS, can be reacted with hydrochloric acid to produce hydrogen sulfide gas. This is a very useful gas, but it is extremely toxic. -

Получение железа из водного раствора сульфата железа (II)
После эксперимента коллеги Termoyad по получению металлического цинка из водного раствора http://chemistry-chemists.com/N3_2016/ChemistryAndChemists_3_2016-P7-1.html решил провести аналогичный эксперимент с железом. Скажу сразу, задача получить железо в качестве реактива не стояла: слава богу, железа пока хватает. Стояла задача ответить на вопрос: можно ли выделить металлическое железо из водного раствора солей химическим способом? Цинк легко образует гидрокомплексы при растворении гидроксида цинка в щелочах, про железо такое не скажешь, поэтому придется обойтись кислыми растворами.
В качестве исходного вещества использовал соль Мора, FeSO4·(NH4)2SO4·6H2O двойной сульфат железа (II) и аммония. Дальше для простоты его формула будет обозначаться как FeSO4 (т.к. сульфат аммония в данном случае практически является балластом). Казалось бы, получить железо из раствора сульфата двухвалентного железа просто, достаточно добавить более активный металл, например, магний. Помните, в школе писали реакции вроде приведенной ниже:
FeSO4 + Mg = MgSO4 + Fe
Так вот, это уравнение можно смело заранее перечеркнуть. Почему?
В водном растворе сульфата железа (II) находится сразу два катиона-окислителя - Fe2+ и H+. Последний образуется в результате гидролиза. Водород расположен в электрохимическом ряду напряжений правее железа, поэтому согласно теории восстанавливаться должны, прежде всего, катионы водорода, а уже потом - катионы железа. На практике, скорее всего, эти процессы будут идти одновременно.
Если катионы водорода будут реагировать с магнием, то равновесие гидролиза сместится вправо - гидролиз приведет к образованию осадка гидроксида железа или основных солей.
Чтобы основные соли не выпадали, нужно добавить кислоту. Решил использовать лимонную кислоту, т.к. она сравнительно слабая, и если и будет реагировать с железом, которое образуется, то не слишком быстро.
Поместил кусочек магния в раствор соли Мора и лимонной кислоты. Началось выделение водорода - не очень сильное, но аэрозоль раствора летел стабильно. Зеленоватый раствор быстро стал светло-серым, со временем - темно-серым, в конце - черным (при разбавлении порции темного раствора она становилась коричневой с зеленоватым оттенком). Растворение магния продолжалось примерно 2 часа - реакция шла сравнительно медленно. Раствор заметно нагрелся.
Вскоре после начала реакции стало заметно образование мелкого порошка железа, который оседал на дно или был взвешен в растворе. Поднес к стакану магнит, образовавшийся порошок железа притянулся к магниту и собрался на стенке стакана. Кусочек магния также примагнитился, т.к. на его поверхности осело железо.

It is used medically to treat iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol, the blue-green heptahydrate is the most common form of this material. All iron sulfates dissolve in water to give the same aquo complex [Fe(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic.
Ferrous sulfate was used in the manufacture of inks, most notably iron gall ink, which was used from the middle ages until the end of the eighteenth century. Chemical tests made on the Lachish letters showed the possible presence of iron. It is thought that oak galls and copperas may have been used in making the ink on those letters. It also finds use in wool dyeing as a mordant. Harewood, a material used in marquetry and parquetry since the 17th century, is also made using ferrous sulfate.

Reversible Reactions
Reversible Reactions: In this lesson we will study reversible reactions. In the above chemical reactions the first positive sign means react with and the second on the product side means 'and' The arrow shows the direction to which the reaction proceeds . Therefore the whole chemical change is represented as; Fe (s) + 2HCl(aq) w FeCl 2 (aq) + H 2 (g) In the second example the reactants are sulphur and Oxygen while the products is Sulphur (IV) oxide since Oxygen gas is limited not excess. The reaction should be presented as S (s) + O2 (g) w SO2(g) Reversible reaction is a chemical reaction in which the products of forward reaction can combine to give back the original reactants. Iron reacts with water to form Iron (III) oxide and hydrogen gas. In the reaction the double arrow means rever... -

Chemicals and Hair Damage
Must see. Very informative! Learn how to maintain healthy hair from a chemist. See the Demo of how to make shampoo. Learn the basic shampoo ingredients in cheep shampoos: water + sulfate + salt = shampoo. But there are sodium free shampoos that do not damage the hair and create dandruff on the scalp. What is in the hairspray? Hairspray ingredients. It has water, alcohol, the resin (glue) and the resin neutralizer: that's a good hairspray; the bad hairspray does not have the neutralizer, which results in a dusty feeling and flakes on the hair. The hairspray manufacturers simply economize on the resin neutralizer to lower the cost of the hairspray and sell it at a higher price. The hairsprays in the bottle are safer than the hairsprays in a can that is half filled wit gas to push the spray s... -

Manganese
Manganese is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is not found as a free element in nature, it is often found in combination with iron, and in many minerals. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. Historically, manganese is named for various black minerals (such as pyrolusite) from the same region of Magnesia in Greece which gave names to similar-sounding magnesium, Mg, and magnetite, an ore of the element iron, Fe. By the mid-18th century, Swedish chemist Carl Wilhelm Scheele had used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite (now known to be manganese dioxide) contained a new element, but they were not able to isolate it. Johan Gottlieb Gahn was the ... -

Nickel
Nickel is a chemical element with the chemical symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel shows a significant chemical activity that can be observed when nickel is powdered to maximize the exposed surface area on which reactions can occur, but larger pieces of the metal are slow to react with air at ambient conditions due to the formation of a protective oxide surface. Even then, nickel is reactive enough with oxygen that native nickel is rarely found on Earth's surface, being mostly confined to the interiors of larger nickel--iron meteorites that were protected from oxidation during their time in space. On Earth, such native nickel is always found in combinati... -

This video provides a tutorial on how to balance chemical equations such as combustion reactions, synthesis and decomposition reactions, single and double displacement reactions in addition to redox reactions under acidic and basic conditions. This video provides plenty of examples and practice problems that will help you to review for your next test or exam.
Here is a list of equations covered in this video:
1. Combustion Reactions:
Methane + oxygen gas yields carbon dioxide and water OR
CH4 + O2 = CO2 + H2O
Propane: C3H8 + O2 = CO2 + H2O
Ethane: C2H6 + O2 = CO2 + H2O
Ethanol: C2H5OH + O2 = CO2 + H2O
Propanol: C3H7OH + O2 = CO2 + H2O
Benzene: C6H6 + O2 = CO2 + H2O
2. Balancing Synthesis & Decomposition Reactions
N2 + H2 = NH3 (nitrogen gas + oxygen gas yields ammonia)
S8 + O2 = SO3 (sulfur + oxygen gas yields sulfur trioxide)
P4 + Cl2 = PCl3 (phosphorus + chlorine gas yields phosphorus trichloride)
Al(OH)3 + CO2 = Al(HCO3)3 (aluminum hydroxide and carbon dioxide gas yields aluminum bicarbonate)
KClO3 = KCl + O2 (potassium chlorate yields potassium chloride and oxygen gas)
Mg3N2 = Mg + N2 (magnesium nitride yields magnesium and nitrogen gas)
3. Al + CuSO4 = Al2(SO4)3 + Cu (aluminum metal and aqueous copper ii sulfate yields aluminum sulfate and copper metal)
K + FeCl2 = KCl + Fe (potassium metal and iron ii chloride yields aqueous potassium chlorine and iron metal)
Na2S + Cl2 = NaCl + S8 (sodium sulfide reacts with chlorine gas to produce sodium chloride and elemental sulfur)
4. How To Balance Double Replacement Reactions:
NaCl + Pb(NO3)2 = PbCl2 + NaNO3
Aqueous sodium chloride reacts with lead (II) nitrate to produce lead (II) chloride and aqueous sodium nitrate
ZnBr2 + Na3PO4 = Zn3(PO4)2 + NaBr
Zinc bromide reacts with sodium phosphate to produce solid zinc phosphate and sodium bromide
Sn(NO3)4 + K3PO3 = Sn3(PO3)4 + KNO3

Reversible Reactions: In this lesson we will study reversible reactions.
In the above chemical reactions the first positive sign means react with and the second on the product side means 'and'
The arrow shows the direction to which the reaction proceeds . Therefore the whole chemical change is represented as;
Fe (s) + 2HCl(aq) w FeCl 2 (aq) + H 2 (g)
In the second example the reactants are sulphur and Oxygen while the products is Sulphur (IV) oxide since Oxygen gas is limited not excess. The reaction should be presented as
S (s) + O2 (g) w SO2(g)
Reversible reaction is a chemical reaction in which the products of forward reaction can combine to give back the original reactants.
Iron reacts with water to form Iron (III) oxide and hydrogen gas.
In the reaction the double arrow means reversible so that rate of forward and backward reactions are the same.
Forward reaction has Iron and steam as the reactants and tri Iron tetra Oxide and hydrogen as products.
Backward reaction has tri Iron tetra oxide and hydrogen as reactants and Iron and steam as products.
Calcium carbonate decomposes to Calcium oxide and carbon (IV) oxide gas.
In the equation when the reaction takes place in a closed system initially it decomposes to form lime (Calcium oxide) and Carbon (IV) oxide. This is the forward reaction.Backward reaction is favoured by accumulation of Carbon (IV) oxide that reacts with lime to form limestone (Calcium Carbonate)
which is given off and a white solid is left behind.
Hydrated Copper (II) crystals lose water of crystallization as shown in the following equation.
When blue crystals of Copper (II) Sulphate are heated in a test tube steam is given off and a white solid is left behind.
When the tube is cooled and a few drops of cold water added the blue colour reappears and the tube becomes hot.
The following experiment is carried out to investigate the chemical equilibrium in Chromate (VI) ion. Click to play the video and observe what happens carefully.
Potassium chromate (VI) solution is orange. When a few drops of dilute hydrochloric acid are added to the solution it turns yellow due to the formation of dichromate (VI) ions (Cr 2 O7 2-). This makes the concentration of hydrogen ions to increase as the acid is added.
An equilibrium is established with more Cr 2 O7 2- in solution than Cr O42- hence orange colour is dorminant.
On adding a few drops of 2M Sodium hydroxide the colour of the solution turns to orange as shown in the equation.
On adding 2M sodium hydroxide OH- ions react with H+ ions to form water. This reduces concentration of H+ ions in the solution shifting the equilibrium to the left.
H+ ions are formed to replace the H+ ions used to form water.
Altering the concentration of any one of the components of the equilibrium mixture disturbs equilibrium by affecting the rate of forward and backward reaction.
This makes the reaction proceed in one direction until a new equilibrium is established.
Note that the arrow showing reversible at equilibrium as shown
Which is different to that of the normal reversible reaction.
When the rate of forward reaction equals the rate of backward reaction a state of balance is reached.
At first D and C dominates to form F and G and then as F and G accumulates reverse reaction starts building up until a state of balance is reached.
At the state of balance the reaction is said to have reached a dynamic equilibrium because reactants and products are simply co existing but there is constant interchange from products to reactants and vice versa.
The following experiment explains chemical equilibrium as a state of balance.
The video clip below shows how to investigate change of colour of indicator in acid alkali media as an example of reversible reactions.Click to play the video and observe what happens carefully.
Phenolphthalein indicator is colourless in water and acid.
It is pink in alkali
In reversible reactions products can form reactants unlike many reactions that are one way.
In a closed system where no reactants or products escape both forward and backward reactions occur at the same time.
As time goes both forward and backward reactions proceed at the same rate. This is called chemical Equilibrium or dynamic equilibrium. The individual atoms and molecules reacting and products do not change in concentration.
You will now learn about the factors affecting rates of reaction.

Reengineering broken book spines working group presents this first of many instructional videos that demonstrate the variations of this innovative book conservation treatment.
WHO IS INVOLVED AND WHY: Jana Dambrogio, Thomas F. Peterson (1957) conservator, Ayako Letizia, conservation assistant, and conservation Associate Kate Beattie of MIT Libraries, Brien Beidler, director of the binding and conservation studio, Charleston Library Society, and Mary Uthuppuru, private conservator and contemporary book artist, Spring Leaf Press. Dambrogio taught the repair to Letizia, Beidler, and Uthuppuru in September of 2014. In early June of 2015 the working group convened in the Wunsch Conservation Lab for a week to perform simple-to-complex variations of the repair on 21 books found in MIT Libraries special and general collections. At that time, the group worked with Beattie to explore ways the repair could be implemented on books found in the Libraries’ circulating collections.
BACKGROUND: About 14 years ago, while studying and conserving several large historic collections ranging from the late medieval period to the mid-20th Century (Fondo Veneto, Sezione II Record Group, Vatican Secret Archives, Vatican City-State; David Lubin Memorial Library, Food and Agriculture Organization of the United Nations, and The British Institute of Florence--Harold Acton Library), Dambrogio realized the value in studying books that received very little treatment or repair. These collections were essentially left in their original condition and contain both bound and flat documents.
She began to think of ways to repair books with a couple goals in mind: preserving their original materials, and minimizing intervention (such as lifting original cover materials or removing spine linings), resulting in a sound treatment that preserves the physical history of the book.
THE TREATMENT:
This treatment is ideal to perform on a book with broken spines or detached boards. It is a type of thin tissue repair. Often the damage occurs at the “joints” and “hinges”, the flexible areas that allow the front and back covers to flex open and close. The value of this innovative treatment option is in its economy, the gentle nature of the repair, its versatility, and the ability to complete each repair step within small amounts of time throughout busy workday schedules. The repair itself uses methyl cellulose, wheat starch paste, various weights of Japanese tissues (often several layers of 5 gram or 10 gram tengujo) , and sometimes textile for badly damaged or heavy books. This treatment is delicate yet sturdy. It is ideal for non-circulating special collections, which can receive a polyester protective jacket after treatment, and must be supported with a book cradle during use. For more than fifty years, variations of a spine reback have been the only option to repair books and their spine covers. The technique is effective but invasive, requiring the conservator to lift or remove original materials to anchor newly added repair materials. The treatment we propose is an innovation in book repair that will offer book conservators an alternative to more invasive techniques. Libraries.mit.edu/preserve
wn.com/Reengineering Broken Book Spines
Reengineering broken book spines working group presents this first of many instructional videos that demonstrate the variations of this innovative book conservation treatment.
WHO IS INVOLVED AND WHY: Jana Dambrogio, Thomas F. Peterson (1957) conservator, Ayako Letizia, conservation assistant, and conservation Associate Kate Beattie of MIT Libraries, Brien Beidler, director of the binding and conservation studio, Charleston Library Society, and Mary Uthuppuru, private conservator and contemporary book artist, Spring Leaf Press. Dambrogio taught the repair to Letizia, Beidler, and Uthuppuru in September of 2014. In early June of 2015 the working group convened in the Wunsch Conservation Lab for a week to perform simple-to-complex variations of the repair on 21 books found in MIT Libraries special and general collections. At that time, the group worked with Beattie to explore ways the repair could be implemented on books found in the Libraries’ circulating collections.
BACKGROUND: About 14 years ago, while studying and conserving several large historic collections ranging from the late medieval period to the mid-20th Century (Fondo Veneto, Sezione II Record Group, Vatican Secret Archives, Vatican City-State; David Lubin Memorial Library, Food and Agriculture Organization of the United Nations, and The British Institute of Florence--Harold Acton Library), Dambrogio realized the value in studying books that received very little treatment or repair. These collections were essentially left in their original condition and contain both bound and flat documents.
She began to think of ways to repair books with a couple goals in mind: preserving their original materials, and minimizing intervention (such as lifting original cover materials or removing spine linings), resulting in a sound treatment that preserves the physical history of the book.
THE TREATMENT:
This treatment is ideal to perform on a book with broken spines or detached boards. It is a type of thin tissue repair. Often the damage occurs at the “joints” and “hinges”, the flexible areas that allow the front and back covers to flex open and close. The value of this innovative treatment option is in its economy, the gentle nature of the repair, its versatility, and the ability to complete each repair step within small amounts of time throughout busy workday schedules. The repair itself uses methyl cellulose, wheat starch paste, various weights of Japanese tissues (often several layers of 5 gram or 10 gram tengujo) , and sometimes textile for badly damaged or heavy books. This treatment is delicate yet sturdy. It is ideal for non-circulating special collections, which can receive a polyester protective jacket after treatment, and must be supported with a book cradle during use. For more than fifty years, variations of a spine reback have been the only option to repair books and their spine covers. The technique is effective but invasive, requiring the conservator to lift or remove original materials to anchor newly added repair materials. The treatment we propose is an innovation in book repair that will offer book conservators an alternative to more invasive techniques. Libraries.mit.edu/preserve

Must see. Very informative! Learn how to maintain healthy hair from a chemist. See the Demo of how to make shampoo. Learn the basic shampoo ingredients in cheep shampoos: water + sulfate + salt = shampoo. But there are sodium free shampoos that do not damage the hair and create dandruff on the scalp. What is in the hairspray? Hairspray ingredients. It has water, alcohol, the resin (glue) and the resin neutralizer: that's a good hairspray; the bad hairspray does not have the neutralizer, which results in a dusty feeling and flakes on the hair. The hairspray manufacturers simply economize on the resin neutralizer to lower the cost of the hairspray and sell it at a higher price. The hairsprays in the bottle are safer than the hairsprays in a can that is half filled wit gas to push the spray stream out, which damages the ozone layer of the earth. Learn how to chose environmentally safe hairsprays. Learn about the pH scale. Learn about the soft protein in the skin and the hard protein in the hair. Why do manufacturers use chemicals on the hair? Because the hair protein is strong and hair has strong chemical bonds, so the chemicals in products open the cuticle to penetrate and work, but the hair cuticle that was opened with the chemicals needs to be closed to be in a good condition. Learn about how the hair gets damaged by the use of flat irons and products that contain alcohol. Learn the boiling water temperature and how the high temperature of the flat iron will burn the hair with excessive heat and how to protect the hair with heat protectors. Learn How to protect the hair from sun damage with UV protectors. What is an alcohol free product? Why do companies use alcohol in products? Learn how to chose hair products based on the ingredients, not the look and smell. Learn how to determine the meaning of the order of any product ingredients and that that the first ingredient in any product the most in the product. The chemistry of frizzy hair; the shampoos are negatively charged and the hair has to be balanced with positively balanced conditioner to avoid frizz on the hair. Do oils have positive charge? What is a sulfate free product: the cleaning agent, the surfactants in the shampoo? Why is salt added to the shampoo? Do wee need salt in the shampoo? Salt is a thickener. Would too much salt in the shampoo make dandruff on the scalp? Learn what to use to get rid of dandruff and what ingredients work. Learn how to fix the dandruff with dandruff shampoo containing zinc. Learn about hair loss and oily scalp, and clarifying shampoo, menthol and other shampoos with beads to clean and exfoliate the fat from the hair pore for the hair to grow. Learn what to use to detangle the hair. Learn how to keep hair extensions untangled. Informative video by guest artist Milca, video by BeautyHealthTravel channel: for cosmetologists, beauty school students, salon professionals, barbers, cosmetology chemists, hairdressers; to learn how to take care of the client's hair.

Manganese is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is not found as a free element in nature, it is often found in combination with iron, and in many minerals. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.
Historically, manganese is named for various black minerals (such as pyrolusite) from the same region of Magnesia in Greece which gave names to similar-sounding magnesium, Mg, and magnetite, an ore of the element iron, Fe. By the mid-18th century, Swedish chemist Carl Wilhelm Scheele had used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite (now known to be manganese dioxide) contained a new element, but they were not able to isolate it. Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, by reducing the dioxide with carbon.

0:29 I find my hair to be unmanageable and I have tried on three separate occasions to blow dry and flat iron my hair. The hair is straight until it hits the ends (about an inch or two deep) and poof!! No matter how many times I run the iron over it or how hot it is the ends of my hair will not get straight nor smooth. I am so frustrated. How do I treat my ends to help with this problem? I have straightened my hair professionally and on my own. big sigh...
4:02 how do you know when you need a trim? Does your hair feel a particular way? OR does it look worn out? In my case my hair looks fine but feels a little tired.
5:19 You mention that it is important that our conditioners are moisture and protein balanced. How can I tell if my conditioners contain both? Are there any specific ingredients that I should look for in my conditioner?
6:35 What is your view of protective styling?
9:01 I am struggling with keeping the ends of my hair moisturized. Have I understood correctly that this does not mean I have to trim them? My hair is in twists or plaits most of the time and I do try to put more product on the ends of my hair . . . . .what do you think the problem is and what should I do to try combat it?
10:20 Can you explain if Mineral Oil in your deep conditioner is great for our hair or not?
12:11 I'd like to know why my hair pattern comes to life when I use a neutralizing shampoo and detangles easier.
13:38 Is henna really ok for the hair? Or other forms of coloring?
15:49 does relaxing your hair ultimately damage your scalp permanently or can it be done and still able to maintain healthy hair? My second question is are there any affordable hair products th (question cut off, please ask again)
17:36 Are you a medical doctor?
18:25 I am a 23 year old African American male. My "bangs" will not grow no matter what.
19:38 Do you ship your products to the UK?
19:52 Can you also talk about: Androgenic Alopecia and Traction Alopecia. have you ever helped people with these problems grow their hair back without using Rogaine. Talk about Rogaine.
22:28 I'm so frustrated with my natural hair and contemplating going back to a relaxer. Please help. I have a few questions. 1. My hair is constantly feeling dry and brittle. Can my hair be sensitive to protein? Are all proteins created equal? 2. I've been having problems with breakage, split ends and mid shaft splits. Is this being caused by the excessive dryness I'm experiencing, and how can I prevent it?
24:04 My hair was soft but I was afraid it was really dry underneath the cones so I stopped using it and all other cones. How do you feel about cones? Do you think my hair would be ok if I used a sulfate poo to remove the cones?

Nickel is a chemical element with the chemical symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel shows a significant chemical activity that can be observed when nickel is powdered to maximize the exposed surface area on which reactions can occur, but larger pieces of the metal are slow to react with air at ambient conditions due to the formation of a protective oxide surface. Even then, nickel is reactive enough with oxygen that native nickel is rarely found on Earth's surface, being mostly confined to the interiors of larger nickel--iron meteorites that were protected from oxidation during their time in space. On Earth, such native nickel is always found in combination with iron, a reflection of those elements' origin as major end products of supernova nucleosynthesis. An iron--nickel mixture is thought to compose Earth's inner core.
