The reaction of aqueus KMnO(4) with H(2)...

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

A

`Mn^(+)` and `O_(2)`

B

`Mn^(2+)` and `O_(2)`

C

`Mn^(2+)` and `O_(3)`

D

`Mn^(4+)` and `MnO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
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.
