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

In acidic medium `KMnO_(4)` is reduced to manganaous ion `(Mn^(2+))` while `H_(2)O_(2)` is oxidized to `O_(2)` :
`{:(2KMnO_(4)+3H_(2)SO_(4)rarrK_(2)SO_(4)+2MnSO_(4)+3H_(2)O+5[O]),(" "H_(2)O_(2)+[O]rarrH_(2)O+[O_(2)]xx5),(bar(2KMnO_(4)+3H_(2)SO_(4)+5H_(2)O_(2)rarrK_(2)SO_(4)+2MnSO_(4)+H_(2)O+5O_(2))):}`
or
`2MnO_(4)^(-) + 5H_(2)O_(2) + 6H^(+) rarr 2Mn^(2+) + 8H_(2)O + 5O_(2)`
