The oxidation of oxalic acid by acidified is an example of autocatalysis.
In oxidation of oxalic acid by potassium permanganate in acidic condition, manganese is in oxidation state meaning it is devoid of electrons. So, when permanganate ion reacts with oxalic acid , its oxidized oxalic acid to give carbon dioxide and water, reducing itself to .The reaction is:
The pink colour of disappears slowly on reaction with oxalic acid, but the rate of disappearance of colour fastens after sometime due to the formation of which acts as auto catalyst for the reaction. Hence, the velocity of the reaction increases.
