Vedclass · Answer

(B) During the electrolysis of an aqueous solution of sodium chloride $(NaCl)$,the following reactions occur:At the cathode,water molecules are reduced in preference to sodium ions because the reduction potential of water is higher than that of $Na^+$ ions.The reaction at the cathode is: $2H_2O(l) + 2e^- ightarrow H_2(g) + 2OH^-(aq)$.Thus,$H_2$ gas is liberated at the cathode.The overall reaction is: $2NaCl(aq) + 2H_2O(l) \xrightarrow{	ext{Electrolysis}} 2NaOH(aq) + Cl_2(g) + H_2(g)$.
