In Which of the following reactions H_(2)O_(2) acts as a reducing agent

Answer»

`PbO_(2)(s) +H_(2)O_(2)(AQ) to PbO (s) +H_(2)O(l) +O_(2)(g) `
`Na_(2)SO_(3)(aq) +H_(2)O_(2)(aq) to Na_(2)SO_(4) (aq) +H_(2)O(l)`
`2KL(aq)+H_(2)O_(2) (aq) to 2KOH (aq) +I_(2)(s)`
`KNO_(2)(aq)+H_(2)O_(2)(aq) to KNO_(3) (aq) +H_(2)O(l)`

Solution :In the following reaction `H_(2)O_(2)` ACTS as a reducing agent.
`PbO_(2(s)) +H_(2)O_(2(aq)) to PbO_((s)) +H_(2)O_((l))+O_(2(g))`
