Description and Uses
Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the molecular 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 ultraalkaline pegmatites.
Sodium Oxalate illustrate the elimination of broadening due to 2nd-?order quadrupolar effects leading to a 30-?fold increase in resolution compared to magic-?angle spinningin NMR of polycrystalline.
