(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 a better oxidising agent than water as discussed below:
(a) `H_(2)O_(2)` oxidises an acidified solution of KI to give `I_(2)` which gives blue colour with starch solution but `H_(2)O` does not
(b) `H_(2)O_(2)` turns black PbS to white `PbSO_(4)` but `H_(2)O` does not
