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

A

`2[Fe(CN)_(6)]^(4-)+ 2H^(+) + H_(2)O_(2) to 2[Fe(CN)_(6)]^(3-)+2H_(2)O`

B

`I_(2)+H_(2)O_(2)+ 2OH^(-) to 2I^(-) + 2H_(2)O +O_(2)`

C

`Mn^(2+) +H_(2)O_(2) to Mn^(4+) + 2OH^(-)`

D

`PbS + 4H_(2)O_(2) to PbSO_(4) + 4H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)O_(2)` acts as an oxidising as well as reducing agent in alkaline medial. The given below reaction show the reducing action action in basic medium
`I_(2)+H_(2)O_(2) + 2H^(-) to 2I^(-) +2H_(2)O +O_(2)`
`2MnO_(4)^(-) + 3H_(2)O_(2) to 2MnO_(2) +3O_(2) +2H_(2)O +2HO^(-)`
