Q.
In oxidation of oxalic acid by KMnO4, the colour of KMnO4 disappears slowly at the start of reaction but disappears very fast afterwards. This is an example of
In the oxidation of oxalic acid by KMnO4, the colour of KMnO4 disappears slowly in the beginning but disappears faster after sometime due to the formation of Mn2+ ions which act as auto-catalyst for the reaction.
