1.	What wil be the products of electrolysis of an aqueous solution of AgNO_(3) with silver electrodes ?
Answer» AG from Ag anode dissolves while `Ag^(+)` from solution gets deposited on cathode. Ag is liberated at cathode and `O_(2)` isliberated at anode. Ag at cathode and nitric acid at anode is liberated. No reaction takes place. Solution :`AgNO_(3)RARR Ag^(+)+NO_(3)^(-)` (AQUEOUS solution) At cathode : `Ag_((aq))^(+)+e^(-)rarr Ag, E^(@)=+0.80 V` `2H_(2)O_((l))+2e rarr H_(2)+2OH^(-), E^(@)=-0.83 V` Since reduction potential of `Ag^(+)` is higher than `H_(2)O`, `Ag^(+)` are REDUCED to Ag. At anode : `Ag rarr Ag_((aq))^(+) + e^(-), E^(@)=-0.80 V` `2H_(2)O rarr O_(2)+4H^(-)+4e^(-), E^(@)= - 1.23 V` Since oxidation potential of Ag is higher than `H_(2)O`, Ag of SILVER anode is oxidised. Theoxidation potential of `NO_(3)^(-)` is lower than `H_(2)O`.
