Oxalic acid dihydrate pka

It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water. Its name comes from the fact that early investigators isolated oxalic acid from flowering plants of the genus Oxalis , commonly known as wood-sorrels. It occurs naturally in many foods. Excessive ingestion of oxalic acid or prolonged skin contact can be dangerous. Oxalic acid has much greater acid strength than acetic acid. The preparation of salts of oxalic acid crab acid [ citation needed ] from plants had been known, at least since , when the Dutch botanist and physician Herman Boerhaave isolated a salt from wood sorrel , akin to kraft process. By , Scheele had shown that "sugar acid" and oxalic acid from natural sources were identical. 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. These diesters are subsequently hydrolyzed to oxalic acid. Approximately , tonnes are produced annually. Historically oxalic acid was obtained exclusively by using caustics, such as sodium or potassium hydroxide , on sawdust , followed by acidification of the oxalate by mineral acids, such as sulfuric acid.

Bacteria produce oxalates from oxidation of carbohydrates.

Oxalic acid dihydrate is mainly used in the chemical field as a reagent, metal surface treatment agent, reducing agent, and intermediate raw material for pharmaceuticals. The substance is also thought to cause some stones if taken in excess. It is a divalent carboxylic acid with two carboxyl groups and acts as an ionized acid in an aqueous solution. Oxalic acid is applied to lighten the color and soften the tone of wood and leather. Oxalic acid has been shown to reduce manganese dioxide MnO 2 in manganese ores to allow the leaching of the metal by sulfuric acid.

It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water.
