Following reactions occur at cathode during the electrolysis of aqueous silver chloride solution: `Ag^(+)(aq)+e^(-)toAg(s),E^(@)=+0.80V,H^(+)(aq)+e^(-)to(1)/(2)H_(2)(g),E^(@)=0.00V` On the basis of their standard reduction electrode potential `(E^(@))` values, which reaction is feasible at the cathode and why? |

Answer» Higher the standard reduction potential of a species, more easily it is reduced at the cathode. As `Ag^(+)(aq)` has greater standard reduction potential, therefore, the reaction that will occur at the cathode is `Ag^(+)(aq)+e^(-)toAg(s)`. |
