Following reactions can occur at cathode during the electrolysis of aqueous silver nitrate solution using Pt electrodes : Ag^(+)""_((aq)) ""^(+e^(-))to Ag""_((s)),E^(@)=0.80V H^(+)""_((aq)) ""^(+e^(-))to 1/2H_(2(g)),E^(@)=0.00V On the basis of theri standars electrode protential values, which reaction is feasible at cathode and why ?
Answer» Solution :`Ag^(+)+E^(-)TOAG(s).` This reaction is feasible because `E^(@)` value for `Ag^(+)//Ag` is more than that of `H^(+)//H_(2).` Higher the value of `E^(@),` more easy it will be to converty ION inot its FREE STATE.
