Why doesn't dissolved salt evaporate?

Answer 1

The dissolution of a salt is such a slow process for a couple different reasons. The amount of time dissolution takes is affected by the surface area and rate of solubility, which varies greatly depending on what the salt is dissolving in.

Answer 2

When salt is dissolved in water, the sodium and chloride ions separate and become surrounded by water molecules. During evaporation, only the water molecules evaporate, leaving the salt ions behind. This is why dissolved salt does not evaporate along with the water.

Answer 3

Because the sun can't evaporate it.

Evaporation is when a liquid changes into a gas. Evaporation is specifically when a liquid turns to gas on its surface without boiling. A liquid also turns to a gas when it boils, which is called vaporization, but this has to occur at a higher temperature than evaporation. A certain amount of energy is required for a solid to change to a liquid, and more is required for a liquid to change to a gas. This usually happens when the temperature increases. However, with a liquid, the molecules bouncing at the surface can sometimes transfer enough energy for the molecule to escape the liquid and become a gas. That means that if salt were a liquid, it could become a gas by either evaporating or vaporizing. The only problem with that is that table salt, which is NaCl or Sodium Chloride, doesn't become a liquid until it reaches 801 °C or 1474 °F and doesn't boil into a gas until it reaches 1413 °C or 2575 °F.

Answer 4

when a solid dissolves in a liquid, it is still solid, just very very small and spread out. And gasses go past solids meaning they collide, but gasses cant carry objects. so when the liquid evaporates, the salt doesn't have anything to be dissolved in, and the vapor doesn't carry it, so just salt is left.

Answer 5

because salt vaporizes at a much higher temperature than water.

Answer 6

As water cools, the hydrogen bonds become stronger and are less able to break and reform. Because they cannot break, they cannot accept any ions from salts.

Answer 7

Salt doesn't evaporate.

If you have salty water the water will evaporate and the salt will remain.

Answer 8

because NaCl dissociates into Na+ and Cl- ions in water

Answer 9

Salt (table salt, sodium chloride) doesn't dissolve slowly in water.

Answer 10

It's too heavy to do so.
