Question

The highly reactive metals like sodium, potassium, magnesium etc are extracted by:

• A. $\text{Electrolysis of their molten Chloride}$
• B. $\text{Electrolysis of their molten Oxide}$
• C. $\text{Reduction by Aluminium}$
• D. $\text{Reduction by Carbon}$

Answer 1

The correct option is A $\text{Electrolysis of their molten Chloride}$

It is because these metals are highly electropositive and cannot be reduced by chemical methods. Hence we use electrolytic reduction of their molten salts for their extraction.
