Answer»

In thesolidstate, ionic compounds such assodium chloridehave their ions fixed in position and therefore these ions cannot move sosolidionic compounds cannotconduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore moltensodium chloridecanconduct electricity..

No. It is not safe to repair electrical appliances outdoors during heavy downpour. This is because rain water contains dissolved salts. Therefore, rain water can conduct electricity. The electrician may get electrical shocks while working outdoors during rain.
