Question
Why do ionic compounds NOT conduct electricity when they are in solid state?
- Their ions are free to move.
- Their ions are held in fixed positions.
- Their electrons are free to move
- Their electrons are held in a fixed state
Hint:
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.
