description
oxalic acid is a strong dicarboxylic acid occurring in many plants and vegetables, usually as its calcium or potassium salts. oxalic acid is the only possible compound in which two carboxyl groups are joined directly; for this reason oxalic acid is one of the strongest organic acids. unlike other carboxylic acids (except formic acid), it is readily oxidized; this makes it useful as a reducing agent for photography, bleaching, and ink removal. oxalic acid is usually prepared by heating sodium formate with sodium hydroxide to form sodium oxalate, which is converted to calcium oxalate and treated with sulfuric acid to obtain free oxalic acid.
concentrations of oxalic acid are pretty low in most plants and plant-based foods, but there’s enough in spinach, chard and beet greens to interfere with the absorption of the calcium these plants also contain.
it is produced in the body by metabolism of glyoxylic acid or ascorbic acid. it is not metabolized but excreted in the urine. it is used as an analytical reagent and general reducing agent.oxalic acid is a natural acaricide used for treatment against varroa mites in colonies with no/low brood, packages, or swarms. vaporized oxalic acid is used by some beekeepers as an insecticide against the parasitic varroa mite.
uses
1. oxalic acid can be mainly used as reducing agent and bleaching agent, mordant for dyeing and printing industry, also used in refining rare metal, the synthesis of various oxalate ester amide, oxalate and grass, etc. 
2. used as analytical reagent. 
3. used as laboratory reagents, chromatography analysis reagent, dye intermediates and standard material.
4. oxalic acid is mainly used for producing drugs such as antibiotics and borneol and solvent for extracting the rare metal, reducing agent and dye, tanning agent, etc. in addition, oxalic acid can also be used for the synthesis of various kinds of oxalate ester, oxalate, and oxamide with diethyl oxalate, sodium oxalate and calcium oxalate having the largest yield. oxalate can also be used for the production of cobalt-molybdenum-alumina catalyst, cleaning of metal and marble as well as the bleaching of textiles.
