The reaction of aqueous `KMnO_(4)` with `H_(2)O_(2)` i 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

`H_(2)O_(2)` is oxidized to `H_(2)O` and `O_(2)` as under `:`
`2KMnO_(4) +3H_(2)SO_(4) + 5H_(2)O_(2) rarr K_(2)SO_(4) + 2MnSO_(4) + 8 H_(2)O + 5O_(2)` or `MnO_(4)^(-) + 5H_(2)O + 6H^(+) rarr 2Mn^(2+) + 8 H_(2)O + 5O_(2)`
