Solid sodium chloride does not conduct electricity because being solid its Na+ and Cl- ions are not moving while sodium chloride solution conducts electicity because it has mobile Na+ and Cl- ions allowing to flow electric current through it.

It is not safe to carry out electrical repairs outdoors during a heavy downpour because rainwater is a conductor of electricity which can cause a short circuit and hence can be fatal.

To carry out electrolysis of water, a few drops of sulphuric acid are (carefully) added to the water because concentrated sulphuric acid is highly acidic which can cause severe burns if mishandled.

Kitchen gas burners are often coated with chromium because chromium protects it from corrosion.
