Since the ions cannot move, ionic solids are non-conductors of electricity. When the solid is melted to a liquid, however, the ions are free to migrate. Therefore, ionic liquids are good conductors of electric current. A conductor is a substance capable of transmitting electricity and/or heat.
The chemicals that cause acid rain are sulfur dioxide and nitrogen oxides . when they rise into the atmosphere they start a very acidic chemical that is later expelled into earth by the clouds
