$KCl_{(aq)}$

Vedclass · Answer

(C) During the electrolysis of an aqueous solution of $KCl$,the ions present are $K^+$,$Cl^-$,$H^+$,and $OH^-$.At the cathode,the reduction potential of $H^+$ $(E^0 = 0.00 \ V)$ is higher than that of $K^+$ $(E^0 = -2.93 \ V)$,so $H_2$ gas is liberated at the cathode.At the anode,the oxidation of $Cl^-$ occurs to form $Cl_2$ gas.Therefore,the electrolysis of $KCl_{(aq)}$ results in the liberation of $H_2$ at the cathode and $Cl_2$ at the anode.

If the passage of current liberates $H_2$ at cathode and $Cl_2$ at anode then the solution is
