Which one of the following is reduced by `H_(2)O_(2)` in alkaline medium?

Options

A. `Fe^(2+)`
B. HOCl
C. `KMnO_(4)`
D. PbS

Answer

C

Explanation

`KMnO_(4)` reduced to `MnO_(2)` in the presence of `h_(2)o_(2)` in alkaline medium. Therefore, `2MnO_(4)^(-)+3H_(2)O_(2)rarr2MnO_(2)+3O_(2)+2H_(2)O+2OH^(-)`
