Cosider the reactions
(i) `H_(2)O_(2) + 2HI to I_(2) + 2H_(2)O`
(ii) `HOCl + H_(2)O_(2) to H_(3)O^(+) + Cl^(-) + O_(2)`
Which of the following statements is correct about `H_(2)O_(2)` with reference to these reactions ? Hydrogen peroxide is ………

Options

A. an oxidising agent in both (i) and (ii)
B. an oxidising agent in (ii) and oxdising agent in(ii)
C. a reducing agent in (i) and oxidising agent in (ii)
D. a reducing agent in both (i) and (ii)

Answer

B

Explanation

Thus, here `H_(2)O_(2)` oxidises `HI` into `I_(2)` hence, it behaves as oxidising agent.

Here, `H_(2)O_(2)` reduces `HOCl` to `Cl^(-1)`, thus, it acts as reducing agent.
