Question

Why oxalic acid is used in redox titration using permanganometry quora?

Answer 1

Answer:

As you may know, HCl is much stronger than Oxalic acid, it will react with KMnO4 to produce the corresponding chlorides of Potassium and Manganese along with liberation of Chlorine gas. This results in deficiency of total amount of KMnO4 available for the reaction with Oxalic acid, thereby affecting your redox titration.

The equation for the reaction is as given below:

KMnO4 + 16HCl ==> 2KCl + 2MnCl2 + 8H2O + 5Cl2
