Oxalate

An oxalate (also ethanedioate) is a salt or ester of oxalic acid. The oxalate ion is (COO)22- and is oxalic acid without the two hydrogen ions.

Consumption of oxalates (for example, the grazing of animals on oxalate-containing plants such as greasewood) may result in kidney disease or even death due to oxalate poisoning.

Much of its other properties resemble oxalic acid.

Examples

- sodium oxalate - Na2C2O4
- calcium oxalate - CaC2O4
- dimethyl oxalate - (CH3)2C2O4
- phenyl oxalate ester - (C6H5)2C2O4
