Name a compound added to molten sodium chloride inorder to lower the melting point of sodium chloride from 801 degree Celsius to 600 degree Celsius .Name the commercial electrolytic cell used.

Answer 1

A common compound added to molten sodium chloride (NaCl) to lower its melting point is potassium chloride (KCl). When mixed with sodium chloride, KCl forms a eutectic mixture that has a lower melting point than the individual components.

The commercial electrolytic cell used for the electrolysis of molten sodium chloride is known as the Downs cell. This cell is specifically designed for the production of sodium metal and chlorine gas through the electrolysis of molten salts.
