Question

can salt evaporate and give the reason why it can or cannot evaporate

Answer 1

Answer:

no salt cannot evaporate because only water gets evaporated.

Answer 2

Salt in seawater is merely dissolved in the water, not chemically bonded to it. When water evaporates (one molecule at a time), only pure water returns to the atmosphere. Salt and other impurities are left behind.

You found little or no almost no evaporation of the salt. The reason is that salts consist of electrically charged atoms (ions) like Na+ and Cl-. They can stick together in a big crystal, like the ones from a salt shaker. Those are too heavy to evaporate
