The reaction of aqueus `KMnO_(4)` with `H_(2)O_(2)` in acidic conditions gives

Options

A. `Mn^(4+) and O_(2)`
B. `Mn^(2+) and O_(2)`
C. `Mn^(2+) and O_(3)`
D. `Mn^(4+) and MnO_(2)`

Answer

B

Explanation

The reaction of aqueous `KMnO_(4) with H_(2)O_(2)` in acidic medium is `3H_(2)SO_(4)+2KMnO_(4)+5H_(2)O_(2) rarr5O_(2)+2MnSO_(4)+8H_(2)O+K_(2)SO_(4)`
In the above reaction, `KMnO_(4)" oxidises" H_(2)O_(2) to O_(2)` and itself `[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.
