प्रश्न
Explain why, an aqueous solution of sodium chloride is not used for the electrolytic extraction of sodium metal.
Advertisements
उत्तर
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.
