Fiberglass boat hull cleaning with oxalic acid
Fiberglass boat hull cleaning with oxalic acid
Mixing up and testing oxalic acid to clean the bottom of a fiberglass boat's hull. Here's the formula. I also show trying bleach and other stuff to get the algae and other plants off. It's amazing what will adhere to the gelcoat. Please watch for the warnings at the end because oxalic acid is potent stuff. I bought some oxalic acid on-line at www.soapgoods.com More wunnerful songs at www.MaximPulse.com I have no connection with soapgoods.com except that I made them a little richer buying their stuff.

Treatment of Honeybees with Oxalic Acid
Treatment of Honeybees with Oxalic Acid
Treating honeybees for Varroa mites is done in the cold weather when there is little or no brood. This ensures the maximum number of mites are affected by the treatment. Here, Glyn Davies of the Devon Beekeepers Association demonstrates the method.

Beekeeping - Oxalic Acid Treatment
Beekeeping - Oxalic Acid Treatment
This is another oxalic acid treatment. The main thing here is that I have made a new device for getting the vapor into the hive. It worked great! It was so much easier to use. It just sat on the top of the hive while I heated the oalic acid in the pipe cap. this has worked great I have now done this treatment several times and have found many many mites in the bottom board tray afterwards. It can be done any time of the year and leaves no toxic residue build up. Just to be clear Oxalic acid is not an approved mitricide in the US even though they have been using it for years in Europe and Canada. Places by the way where they have less mite problems and CCD.... My Disclaimer: Oxalic acid is approved for use as Wood Bleach for cleaning wood. My intention is to clean my wooden ware, it just so happens that this also kill mites.....

Beekeeping - Oxalic Acid Treatment
Beekeeping - Oxalic Acid Treatment
This is my first attempt to do an Oxalic Acid Treatment. Oxalic acid is used to bleach wood and is not approved for mite treatment in the US. So I would never recomend it.... I will say that a side affect of this bleach treatment is that it did kill hundreds of mites. This method of vaporising is prefered over the trickle method because it can be done more than once a season with out causing ill effects to the bees. oxalic acid is a natural organic compound andleaves no toxic residue biuld up in the hive unlike other mitricides.

REDOX : Oxalic acid oxidation with potassium permanganate
REDOX : Oxalic acid oxidation with potassium permanganate
Oxalic acid is oxidized by potassium permanganate according to the following equation : 5 H2C2O4 + 2 KMnO4 + 3 H2SO4 → K2SO4 + 2 MnSO4 + 10 CO2 + 8 H2O First a concentrated solution of oxalic acid is prepared inside the left cylinder by adding oxalic acid dihydrate to water until no more dissolves. Then concentrated potassium permanganate solution is added to water inside the Erlenmeyer flask and shaken to dissolve it completely. A little sulfuric acid 98% is added to heat the solution up. The oxalic acid solution is added to the Erlenmeyer flask and apparently no reaction occurs as proven by no change in color, but this is not correct, the reaction is taking place but very slowly. According to collision theory only a few collisions are effective to the reaction developing and in this reaction two factors slow down the reaction : I the conformation of the oxalate2- ion which reduces the utile collisions at only 10 degrees around the carbon-carbon bond II the low concentration of sulfuric acid in the solution ( few molecules = few collisions ) In order to speed the reaction up the concentration of sulfuric acid is increased by adding 25 ml 98% sulfuric acid more. The reaction is run to completion within seconds and the solution changes color form the deep violet of permanganate ion to the light pink - colorless manganese2+ while carbon dioxide bubbles out of the solution.

How to Clean Rust From Glass [Oxalic Acid Method]
How to Clean Rust From Glass [Oxalic Acid Method]
In this video I will show you how to clean rust stains of of glass with oxalic acid. Oxalic acid can be bought at most home inprovement stores as wood bleach. To remove rust just put a spoon full of the oxalic acid into water and dissolve. Pour that solution into your dirty beakers and let sit untill all of the rust has dissolved. Remember to neutralize the left over solution before you discard it. Thanks for watching
