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

Answer» (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
