1 M aqueous solution of NaCl undergo electrolysis if 50 mA current is passed for 12 hours assume current efficiency is 25%. The total volume of gas produced at standard state is. NaCl (aq) solution undergoes electrolysis as:

NaCl(aq) àNa+ + Cl-

        H2O à H+ + HO-

Reactions:

At cathode: 2H+ + 2e-à H2(g)

At anode:   2Cl-à Cl2(g) + 2e-
