Write balanced equations for the reactions at the anode and cathode during the extraction of: I. sodium; II. aluminium. (iii) Explain briefly why extraction of aluminium is considered environmentally friendly while that of sodium is not.

Sodium is silvery-white in appearance with metallic lusture. It is soft and easily cut by a knife. It is lighter than water. It is a good conductor of heat and electricity. Its melting point is 97.5 °C and its boiling point is 883 °C. Chemical properties: 1. Action with air: sodium tarnishes in air due to formation of oxide. 4Na + O 2 → 2Na 2 O

If an aqueous solution of sodium chloride is used in electrolysis, sodium metal, formed at cathode, will immediately react with water in the aqueous solution to form sodium hydroxide because sodium is a highly reactive metal. Hence, it is important to use molten sodium chloride and not its aqueous solution in electrolytic extraction.
