Oxalic acid
Oxalic acid (ethanedioic acid, chemical formula - C2H2O4, or HOOC-COOH) is a strong chemical organic acid belonging to the class of saturated carboxylic acids. It is the simplest dibasic carboxylic acid.
Under standard conditions, oxalic acid is a dibasic saturated carboxylic acid, which is a white crystalline substance.
Oxalic acid and oxalates are used in the textile and leather industries as mordants. They serve as components of anode baths for the deposition of metal coatings - aluminum, titanium and tin.
Oxalic acid and oxalates are reagents used in analytical and organic chemistry. They are included in compositions for removing rust and oxide films on metal; used for precipitation of rare earth elements from solution.
Oxalic acid derivatives - dialkyl oxalates, mainly diethyl oxalate and dibutyl oxalate - are used as cellulose solvents. A number of oxalic acid esters and compounds of the group of substituted phenols are used as chemiluminescent reagents.
Oxalic acid is used in beekeeping to protect against Varroa mites.
