Oxalate - Wikipedia

Oxalate (IUPAC: ethanedioate) is the dianion with the formula C 2 O 2− 4, also written (COO) 2− 2.Either name is often used for derivatives, such as salts of oxalic acid, for example sodium oxalate Na 2 C 2 O 4, or dimethyl oxalate ((CH 3) 2 C 2 O 4).Oxalate also forms coordination compounds where it is sometimes abbreviated as ox.. Many metal ions form insoluble precipitates with oxalate
