An acidic solution of hydrogen peroxide behaves as an oxidising as well as reducing agent. Illustrate it with the help of a chemical equation.

Answer»

Solution :The FOLLOWING chemical equation indicate the oxidising and reducing nature of `H_2O_2`.
(i) `H_2O_2`, oxidises acidified KI to iodine.
`2KI + H_2O_2 + H_2SO_4 toI_2+ K_2SO_4 + 2H_2O`
(ii) `H_2O_2` REDUCES `KMnO_4` to `MnO_2` in ALKALINEMEDIUM.
`2KMnO_4 + 3H_2O_2 to 2MnO_2 + 2KOH + 3O_2 + 2H_2O`
