1.	In which of the following reactions `H_(2)O_(2)` acts as a reducing agent ?A. `H_(2)O_((l)) + NH_(3(aq)) hArr OH_((aq))^(-) + NH_(4(aq))^(+)`B. `H_(2)O_((l)) + H_(2)S_((aq)) hArr H_(3)O_((aq))^(+) + HS_((aq))^(-)`C. `H_(2)O_((l)) + H_(2)O_((l)) hArr H_(3)O_((aq))^(+) + OH_((aq))^(-)`D. `H_((aq))^(+) + OH_((aq))^(-) hArr H_(2)O_((l))`
Answer» Correct Answer - A `H_(2)O` acts as a Bronsted acid and gives a proton to react with a base. `underset("acid")(H_(2)O)+underset("base")(NH_(3))hArr OH^(-)+NH_(4)^(+)` In `underset("base")(H_(2)O)+underset("acid")(H_(2)S)to H_(3)O^(+)+HS^(-), H_(2)O` acts as a base with `H_(2)S`.
