Abstract:

Ionic compounds can only conduct electricity if their ions are free to move. So ionic compounds do not conduct electricity when they are solid, but they do conduct electricity when they are dissolved in water or when they are melted.

Answer:
Ionic compounds can conduct electricity when dissolved in water or melted because the ions are free to move.
