Which of the following equation depicts reducing nature of `H_(2)O_(2)`?

Options

A. `2[Fe(CN)_(6)]^(4-)+2H^(+)+H_(2)O_(2)`
`rarr 2[Fe(CN)_(60)]^(3-)+2H_(2)`
B. `I_(2)+H_(2)O_(2)+2OH^(-) rarr 2I^(-)+2H_(2)O+O_(2)`
C. `Mn^(2+)+H_(2)O_(2) rarr Mn^(4+)+2OH^(-)`
D. `PbS+4H_(2)O_(2) rarr PbSO_(4)+4H_(2)O`

Answer

B

Explanation

In the reaction
`I_(2)+H_(2)O_(2)+2OH^(-) rarr 2I^(-)+2H_(2)O+O_(2)`
`H_(2)O_(2)` acts as a reducing agent as `I_(2)` is reduced to `I^(-)`
