$NaCl(aq)$

Vedclass · Answer

(C) During the electrolysis of aqueous sodium chloride $(NaCl(aq))$,the following reactions occur:At the cathode: $2H_2O(l) + 2e^- \rightarrow H_2(g) + 2OH^-(aq)$ (Reduction of water occurs because $E^\circ_{H_2O/H_2} > E^\circ_{Na^+/Na}$).At the anode: $2Cl^-(aq) \rightarrow Cl_2(g) + 2e^-$ (Oxidation of chloride ions occurs).Thus,$H_2$ gas is liberated at the cathode and $Cl_2$ gas is liberated at the anode.

Which of the following solutions,upon electrolysis,produces $H_2$ gas at the cathode and $Cl_2$ gas at the anode?
