Why in the redox titration of  kMnO(4) ...

Why in the redox titration of  `kMnO_(4)` vs oxalic acid, we heat oxalic acid solution before starting the titration?

Text Solution

Verified by Experts

The correct Answer is:
N/a
As we know with increase in tempera.ure rate ol reaction increases, Hence, we heat oxalic acid solution before starling of titration to increase the rate of decolourisation.
