In this video we make a sodium oxalate, a simple primary standard for the standardization of potassium permanganate titrant.

The reaction is pretty simple. 120g of oxalic acid is dissolved in 300mL of boiling water and mixed with 80g of sodium hydroxide dissolved in 200mL of water. The sodium oxalate precipitates out and is allowed to cool. It is filtered and dried.

Sodium oxalate will be used in an upcoming video to standardize potassium permanganate solution that will in turn be used to titrate hydrogen peroxide.
