Answer» Correct Answer - B The reaction of aqueous `KMnO_(4)` with `H_(2)O_(2)` in acidic medium is `3H_(2)SO_(4) + 2KMnO_(4) + 5H_(2)O to 5O_(2) + 2MnSO_(4) + 8H_(2)O + K_(2)SO_(4)` In the above reaction, `KMnO_(4)` with `H_(2)O_(2)` to `O_(2)` and itself i.e., `[MnO_(4)^(-)]` gets reduced to `Mn^(2+)` ion as `MnSO_(4)`. Hence, aqueous solution of `KMnO_(4)` with `H_(2)O_(2)` yields `Mn^(2+)` and `O_(2)` in acidic conditions. |
