Oxalic acid (COOH)2 - Formula, Properties, Structure
Oxalic acid is mainly manufactured by the oxidation of carbohydrates or glucose using nitric acid or air in the presence of vanadium pentoxide. A variety of precursors can be used including glycolic acid and ethylene glycol. A newer method entails oxidative carbonylation of alcohols to give the diesters of oxalic … Visa mer Oxalic acid is an organic acid with the systematic name ethanedioic acid and formula HO2C−CO2H. It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water. Its name … Visa mer Acid-base properties Oxalic acid's pKa values vary in the literature from 1.25–1.46 and 3.81–4.40. The 100th ed of the … Visa mer The conjugate base of oxalic acid is the hydrogenoxalate anion, and its conjugate base (oxalate) is a competitive inhibitor of the lactate dehydrogenase (LDH) enzyme. LDH catalyses the conversion of pyruvate to lactic acid (end product of the fermentation … Visa mer The preparation of salts of oxalic acid (crab acid) from plants had been known, at least since 1745, when the Dutch botanist and physician Herman Boerhaave isolated a salt from wood sorrel. By 1773, François Pierre Savary of Fribourg, Switzerland had isolated oxalic acid … Visa mer Anhydrous Anhydrous oxalic acid exists as two polymorphs; in one the hydrogen-bonding results in a chain-like … Visa mer Biosynthesis At least two pathways exist for the enzyme-mediated formation of oxalate. In one pathway, oxaloacetate, a component of the Visa mer Oxalic acid's main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent). Its utility in rust removal agents is due to its forming a stable, … Visa mer WebbThe molecular mass of oxalic acid =126 g.
