Answer:
Explanation:
Molten sodium chloride conducts electricity due to the presence of free ions.
In solid-state, ionic compounds does not have any free ions , so they will not conduct electricity. But when melted, the molten ionic compounds will have free ions [ both cations with a positive charge(s) and anions with a negative charge(s) ] and can conduct electricity.
