Sodium oxalate, or disodium oxalate, is the sodium salt ofoxalic acid with the formula Na2C2O4. It is usually a white, crystalline, odorless powder, that decomposes at 250–270 °C. 
Disodium oxalate can act as areducing agent, and it may be used as a primary standard for standardizingpotassium permanganate (KMnO4) solutions. 
The mineral form of sodium oxalate isnatroxalate. It is only very rarely found and restricted to extremely sodic conditions of ultra-alkalinepegmatites. 
Sodium oxalate can be prepared through the neutralization of oxalic acid with sodium hydroxide (NaOH) in a 1:2 acid-to-base molar ratio. Half-neutralization can be accomplished with NaOH in a 1:1 ratio which produces NaHC2O4, monobasic sodium oxalate or sodium hydrogenoxalate.
