8.Properties:
Oxalic acid is an organic compound with the formula H2C2O4 (also written as HOOCCOOH). It is a colorless crystalline solid that forms a colorless solution in water. It is classified as a dicarboxylic acid. In terms of acid strength, it is much stronger than acetic acid. Oxalic acid is a reducing agent and itsconjugate base, known as oxalate (C2O42−), is a chelating agent for metal cations. Typically, oxalic acid occurs as the dihydrate with the formula H2C2O4·2H2O. Excessive ingestion of oxalic acid or prolonged skin contact can be dangerous.
9.Usages:
Pharmaceutical industry,precipitating agent of rare earth elements,bleaching,metal and marble polish,cleanser removing stains,tanning industry,printing and dyeing catalytic agent,anti-shrinkage finishing of paper,manufacturing oxalates.
