(a). Why sodium chloride is added during electrolysis of fused anhydrous magnesium chlroride?
(b). Why magnesium oxide is used for the lining of steel making furnace?

Text Solution

Verified by Experts

a. Sodium chloride `(NaCl)` is added to lower the fusion temperature of magnesium chloride `(MgCl_(2))` and to make the mixture as a good conductor of electricity.
b. `MgO` is used for the lining of steel making funase as it forms slag with the impurities and thus helps in removing them from iron.
