Sodium metal and chlorine gas can be obtained with the electrolysis of molten sodium chloride.
Electrolysis of aqueous sodium chloride yields
hydrogen and chlorine, with aqueous sodium hydroxide remaining in solution.
The reason for the difference is that the reduction of Na+ (E° = –2.7 v) is energetically more difficult than the reduction of water (–1.23 v).

Electrolysis➫ The producing of chemical changes by passage of an electric current through an electrolyte.
➧The three methods of electrolysis of sodium chloride are:
[1] Dilute aqueous sodium chloride solution produces hydrogen at the cathode & oxygen at the anode.
[2] Concentrated aqueous sodium chloride solution produces hydrogen at the cathode & chlorine at the anode.
[3] Aqueous solutions of intermediate concentrations may produce both chlorine & oxygen at the anode.
❱ Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.
