Discoloration of the solution of potassium permanganate
name: Oxidation of potassium permanganate
This process is a combination of two reactions. On the one hand, this is an ordinary redox reaction, on the other hand, there is a catalytic disproportionation of hydrogen peroxide in the presence of potassium permanganate.
The release of oxygen is due to the occurrence of the catalytic disproportionation of the unstable peroxide oxygen. Discoloration of potassium permanganate is due to its reduction to manganese sulfate.
