Question

Why do ionic compounds NOT conduct electricity when they are in solid state?

  1. Their ions are free to move.
  2. Their ions are held in fixed positions.
  3. Their electrons are free to move
  4. Their electrons are held in a fixed state

hintHint:

In solid-state ions are fixed in their positions.

The correct answer is: Their ions are held in fixed positions.


    • Ionic compounds dissolve in water.
    • Ionic compounds conduct electricity in a molten state.
    • Ions are free to move in a molten state.
    • In solid-state they do not conduct electricity as ions are held in fixed positions.
