Question

Explain why does sodium chloride, a nonconductor , of electricity in the solid state, becomes a good conductor of electricity when dissolved in water or in the molten state.

Answer 1

Answer:

In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.
