(i) Draw the gas phase and solid phase structure of `H_(2)O_(2)`.
(ii) `H_(2)O_(2)` is a better oxidising agnet than water . Explain .

Explanation

(ii) `H_2 O_2` is better oxidising agent than water because
(a) it oxidises an acidified KI solution to `I_2` which give blue colour with starch solution but water does not.
(b) `H_2 O_2` turns black PbS to white `PbSO_4` but water does not.
