Answer to Question #37592 in Inorganic Chemistry for shahin

Question

Why redox titration with sodium oxalate and potassium nitrate testing should not exceed 70 or 80 ° C heat and sulfuric acid to a solution of sodium oxalate?

Answer 1

Potassium nitrate is not used as oxidizer in the redox titrations. Maybe you meant potassium permanganate. The temperature is controlled to avoid the thermal decomposition of an oxalate.
