The salt doesn't evaporate, so it gets left behind in the bowl. Water evaporates in the same way from lakes, rivers, and oceans. The water heats up, turns into a gas, and then condenses to fall back down as rain. See if you can distill fresh water from other liquids like cola, orange juice or even applesauce.

The dissolved salt consists of electrically charged particles (ions), Na+and Cl-. It takes a lot of energy to remove a charged particle from water and put it in gas. Now you might wonder why a Na+and a Cl- don’t stick together to make a neutral (no-charge) molecule, which could evaporate more easily.

The salt doesn't evaporate. It dissolves in the water, but it doesn't disappear. It merely goes into solution and stays with the water. If you heat the salt solution or let it stand in the open, the water will evaporate leaving the salt beh...
