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.

With an accout for my. Oxalic acid is the chemical compound with the formula H 2 C 2 O 4. It is a relatively strong organic acid , being about 10, times stronger than acetic acid. The di-anion, known as oxalate, is also a reducing agent as well as a ligand in coordination chemistry. Many metal ions form insoluble precipitates with oxalate, a prominent example being calcium oxalate, which is the primary constituent of the most common kind of kidney stone. Although it can be readily purchased, oxalic acid can be prepared in the laboratory by oxidizing sucrose using nitric acid in the presence of a small amount of vanadium pentoxide as a catalyst. Typically oxalic acid is obtained as the dihydrate. This solid can be dehydrated with heat or by azeotropic distillation. Oxalic acid exhibits many of the reactions characteristic of other carboxylic acids. It forms esters such as dimethyloxalate m. It forms an acid chloride called oxalyl chloride.

It is a white crystal or crystalline powder at room temperature. Click share is defined as the total number of clicks for all companies during the period divided by the number of clicks for each company. It forms esters such as dimethyl oxalate m. It usually binds as a bidentate ligand forming a 5-membered MO 2 C 2 ring. Gosselin et al. Transport Vehicles. Plants of the genus Fenestraria produce optical fibers made from crystalline oxalic acid to transmit light to subterranean photosynthetic sites. The products are useful in various fields, including electronic, cosmetic, polymeric, pharmaceutical, and medical care. Toggle limited content width.
