Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following happens when water evaporates?
A
Dissolved salts in the water also evaporate
B
Table salt is harvested
C
Dissolved salts rise to the surface of the water
D
Dissolved salts in the water are left behind
Explanation: 

Detailed explanation-1: -When that water evaporates, the salt is left behind. The fresh-water vapor then condenses into clouds, many of which drift over land. Precipitation from those clouds fills lakes, rivers, and streams with fresh water.

Detailed explanation-2: -The water molecules that evaporate become a gas called water vapor. Only the water evaporates, leaving the sodium and chloride ions behind. The sodium and chloride ions attract each other and re-form salt crystals.

Detailed explanation-3: -When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules.

Detailed explanation-4: -Evaporation is the process that changes liquid water to gaseous water (water vapor).

Detailed explanation-5: -When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate. Only the solute will remain in the evaporating dish.
