What are the uses of evaporative salts?

Answer : Evaporative salts are majorly used as common salts or halites, which are highly and widely used to preserve foods, dye fabric, and de-ice roads.

Explanation : Evaporative salts are produced by evaporation of the sea water hence it is named as evaporative salts. These are mainly extracted through evaporation from seawater. The salts from shallow ponds where the seawater gets collected in a land, which is later harvested and then purified.

A solid can evaporate by melting into a liquid, which then evaporates; or by changing instantly into a vapor, or subliming. The rate of evaporation of a substance depends on its surface temperature, the pressure, and the humidity. Evaporation is the procedure by which a liquid or a solid changes into a vapor. A substance may evaporate by changing into a vapor at the surface, as when water evaporates from an uncovered dish.
