In which of the following reactions `H_(2)O_(2)` is a reducing agent?

A

`2FeCl_(2)+2HCl+H_(2)O_(2) rarr 2FeCl_(3)+2H_(2)O`

B

`Cl_(2)+H_(2)O_(2) rarr 2HCl+O_(2)`

C

`2HI+H_(2)O_(2) rarr 2H_(2)O+I_(2)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
`overset(0)(Cl_(2))+H_(2)O_(2)rarr 2overset(-1)(HCl)+O_(2)`. In this reaction chlorine is reduced from zero to `-1` oxidation state.
