Sodium oxalate is typically used as a reducing agent in most natural metabolic processes in plants and vegetables, and may also often be used as a primary standard for the standardization of potassium permanganate solutions.

Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na2C2O4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO4) solutions.
