Question

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

Ionic compounds have strong forces of attraction between them in solid state.There is no free electrons in it in the solid state. But in molten state there a free electrons which helps to conduct electricity. So ionic compound do not conduct electricity in solid state.
