Sodium oxalate or disodium oxalate is the sodium salt of oxalic acid with the formula Na2C2O4. It is usually a white crystalline odorless powder that decomposes at 250–270 °C.Disodium oxalate can act as a reducing agent and it may be used as a primary standard for standardizing potassium permanganate (KMnO4) solutions.The mineral form of sodium oxalate is natroxalate. It is only very rarely found and restricted to extremely sodic conditions of ultra-alkaline pegmatites.
