An aqueous solution of NaCl on electrolysis gives H_2(g), Cl_2(g) and NaOH according to the reaction:2Cl^(-)(aq) + 2H_2O = 2OH^(-) (aq) + H_2(g) + Cl_2(g)A direct current of 25 amp with a current efficiency of 62% is passed through 20 litres of NaCl solution (20% by weight). Write down the reactions taking place at the anode and at the cathode. How long will it take to produce 1 kg of CI_2? What will be the molarity of the solution with respect to hydroxide ions? (Assume no loss due to evaporation.)
