The emf of the cell involving the following reaction, `2Ag^(+) +H_(2) rarr 2Ag +2H^(+)` is `0.80` volt. The standard oxidation potential of silver electrode is:-A. `-0.80` voltB. `0.80` voltC. `0.40` voltD. `-0.40` volt |

Answer» Correct Answer - A `E_("cell")^(@)=E_("cathode")-E_("andoe")0.80= E_(Ag^(+)//Ag)^(@)-E_(H_(2)//H^(+))^(@)` `0.80 = E_(Ag^(+)//Ag)-0` `E_("oxidation")^(@)= - E_("red")^(@)= -0.80 V` |
