Question

An aqueous solution of sodium chloride is not used for electrolytic reduction of sodium metal. Why?

Answer 1

An aqueous solution of sodium chloride is not used for electrolytic reduction of sodium metal because if we electrolyse an aqueous solution of sodium chloride, then as soon as sodium metal is produced at the cathode, it will react with water to form sodium hydroxide. So electrolysis of aqueous sodium chloride solution will produce sodium hydroxide and not sodium metal.
