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

Explanation

(b) `H_(2)O_(2)` has oxidised HI to `I_(2)` (A) and has reduced HOCl to `Cl^(-)` ion in (B).
