Answer» Correct Answer - C Oxidising nature of `H_(2)O_(2)` means it oxidises other substance and itself gets reduced. In such reactions `O_(2)` is not evolved. In (a), `MnO_(4)^(-)` gets reduced from `Mn^(7+)` to `Mn^(2+)`. In (b), `Fe^(3+)` gets reduced to `Fe^(2+)`. In (c ), `I^(-)` gets oxidised to `I_(2)`. In (d), `KIO_(4)` gets reduced from `I^(7+)` to `I^(5+)`. |
