Question

9. Why do ionic compounds not conduct electricity
in solid state but conduct electricity in molten
and aqueous state ?​

Answer 1

Answer:

Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Answer 2

Answer:

Because in solid state the molecules are very close and there is no space for conduction of ionic compounds
