Specific Gravity of oxalic acid

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 acids in organic compounds. The almost infinite esters provide a wide range of viscosity, specific gravity, vapor pressure, boiling point, and other physical and chemical properties for the proper. Oxalic acid undergoes many of the reactions characteristic of other carboxylic acids. It forms esters such as dimethyl oxalate (m.p. 52.5 to 53.5 °C (126.5 to 128.3 °F)). It forms an acid chloride called oxalyl chloride.. Oxalate, the conjugate base of oxalic acid, is an excellent ligand for metal ions, e.g. the drug oxaliplatin.. Oxalic acid and oxalates can be oxidized by permanganate in. 1910.1200). Oxalic Acid, anhydrous (CAS no. 144- 62 -7) is listed on the Canadian DSL Oxalic Acid, dihydrate (CAS 6153- 56 -6) is not listed on the Canadian DSL. EINECS no. for Oxalic Acid, anhydrous: 205- 634 -3 EINECS no. for Oxalic Acid, dihydrate: unlisted Oxalic Acid, dihydrate is on the inventory lists for China, Japan, and Philippi nes

Oxalate acts as a chelating agent for metal cations. Typically, oxalic acid also exists in the form of dihydrate with the formula H2C2O4.2H2O. Ingestion of oxalic acid through skin contact or orally proves to be fatal. Scheele in 1776 discovered the oxalic acid
