Hydrogen peroxide is a powerful oxidising agent.
It is an electron acceptor in acidic and alkaline mediums .
`H_(2)O_(2) + 2H^(+) + 2e^(-) rarr H_(2)O` (in acidic medium )
`H_(2)O_(2) + 2e^(-) rarr 2OH^(-)` (in alkaline medium)
It can also act as reducing agent towards powerful oxidising agents . `H_(2)O_(2) rarr 2H^(+) + O_(2) + 2e`
In alkaline medium , however , its reducing nature is more effective . `H_(2)O_(2) + 2OH^(-) rarr 2H_(2)O + O_(2) + 2e^(-)`
In which of the following reactions , `H_(2)O_(2)` acts a reducing agent ?

A

`PbO_(2) + H_(2)O_(2) rarr PbO + H_(2)O + O_(2)`

B

`Na_(2)SO_(3) + H_(2)O_(2) rarr Na_(2)SO_(4) + H_(2)O`

C

`2Kl + H_(2)O_(2) rarr 2KOH + I_(2)`

D

`KNO_(2) + H_(2)O_(2) rarr KNO_(3) + H_(2)O`
