Beekeeping Through the Eyes of a Biologist. Note that all formulas are case-sensitive. wt. One possible advantage is that bees don’t like the taste of glycerin, and may thus be less likely to lick up the acid. I gladly accept  gifts of appreciation from my readers and supporters. Find pure quality molecular weight of oxalic acid that retain acidic properties and serve purposes optimally at Alibaba.com. oxalic acid can be made by fusing sawdust (or other forms of cellulose) with a mixture of sodium hydroxide and potassium hydroxide. The above dose applies about half as much OA to the bees, but the greater amount of solution likely results in better dispersal. It is a primary standard and has the molecular formula COOH-COOH.2H2O. Molecular Weight: 254.19. All donations go towards website maintenance, bee research costs (typically tens of thousands of dollars per year), re-donations to fund research by others, and a small amount to partially offset the incredible number of hours that I spend in research and writing. Its equivalent mass is 126/2 = 63 as its n factor is 2 as per the following reaction: COOH-COOH → 2CO2 + 2H+ + 2e–. • MnO2 + C2H2O4 = MnO + H2O + 2CO2. molecular weight of oxalis acid is 126 , then the weight of oxalis acid required to neutralise 100 ml of 1N NaoH is, This site is using cookies under cookie policy.

Update 15 July 2019: A recent study by Toomema (https://doi.org/10.1080/00218839.2018.1486695), suggests that the oxalic dribble can be equally effective if a more dilute solution of OA in water alone (5 g OA dihydrate/1 L water) is applied at the greater rate of 20 mL/comb space of bees, rather than 5 mL. Oxalic acid, or H2C2O2, is a highly acidic, organic compound. Since I am not a 501(c)(3), your gifts are not tax deductible. Crystalline oxalic acid is H O O C − C O O H. 2 H 2 O. C. 5 3.
