Action of acidified potassium permanganate on hydrogen Peroxide.

Answer Text:
Action of acidified potassium permanganate on Hydrogen Peroxide:
- The overall reaction is a Redox reaction

Note:
-The oxidation number of manganate ions in #KMnO_4# decreases from 7 to 2 (in #Mn^(2+)#) hence reduction; while oxidation number of hydrogen increases from -1 (in #H_2O_2#) to 1 (in #H^(+)#); hence oxidation;
-Thus the acidified potassium manganate (VII) oxidizes hydrogen peroxide to water and hydrogen;
