Question

write the reaction between oxalic acid and KMnO4 ​

Answer 1

Answer:

Potassium permanganate is standardized against pure oxalic acid. It involves a redox reaction. Oxalic acid is oxidised to carbon dioxide by KMnO4, which itself gets reduced to MnSO4.

Explanation:

Why in the redox titration of KMnO4 vs oxalic acid, we heat oxalic acid solution before starting the titration? Solution : The reaction is very slow at room temperature. By raising the temperature, the reaction rate increases.
