Question

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`

Answer 1

Correct Answer - B
In (B) `H_(2)O_(2)` (O.N of O =-1) is getting oxidised to `O_(2)` (O.N of O = 0) and thus acts as a reducing agent.
