Sodium oxalate is a sodium salt of oxalic acid which can act as a reducing agent. Disodium oxalate is frequently referred to as sodium oxalate . The polyatomic ion of oxalate has a negative two charge, there can be no other compound consisting solely of sodium and oxalate other than disodium oxalate . Therefore, the prefix "di" is often dropped.
