The boiling point of salt is much much higher than the boiling point of water. So the salt stays behind while the temperature of the water remains at the boiling point of water.

Will salt water tap water or pond water evaporate first?

Salt water will evaporate first. Salt takes up space so to speak and there's less "water" to evaporate and so it seems to evaporate faster.


How do you use the salt in the oceans?

Evaporate the water by sunpower and by boiling. The salt will remain.


Why does salt not evaporate with water?

Salt does not evaporate with water because it has a much higher boiling point than water. When water evaporates, it leaves behind the salt, which remains solid. Salt can be dissolved in water, but it does not evaporate along with the water molecules.


Will water with salt evaporate faster than water with out salt?

No, it will evaporate slower. When salt or another nonvolatile solute is added to water it raises the boiling point, making it more difficult to evaporate.


Can you boil salt and water and get the salt back?

Because the boiling point for salt ( NaCl ) is 1413 degrees Celsius, and the boiling point for water ( h2o) is 100 degrees Celsius, it is possible to boil salt water, and have the water evaporate, and the salt remain .


What will you get if you boil salt water?

If you boil it, the water will evaporate. If you leave it boiling long enough, you should only have salt left.


Why doesn't the salt evaporate in water?

The boiling point of sodium chloride is at 801 oC !


How do you seperate salt from soil?

dissolve it is water and filter it to remove the soil before boiling to allow the water to evaporate in order to get your salt


How do you get salt out of water after it is dissovled?

The easiest way is to evaporate the water off which may be speeded up by boiling


Does boiling salt water leave residue?

Yes it does. The water evaporates off leaving salt crystals behind. Depending on how fast you evaporate the water, different sizes of crystals are formed. The slower you evaporate, the larger the crystals.


Which water evaporate fast salt water or pure water?

pure waterDiscussionDissolving something in water which does not evaporate easily will make the mixed solution less likely to evaporate than pure water. The more stuff you add to it, the less likely it will evaporate.Adding salt to water makes ions in solution and these ions reduce the vapor pressure of the solution compared to pure water. The lower the vapor pressure of a liquid or solution, the slower it will evaporate. This effect is also related to boiling point elevation and freezing point depression.


In the process of distillation why does salt not evaporate?

Salt does not evaporate during distillation because its boiling point is much higher than that of water. Distillation separates substances based on the differences in their boiling points, so salt remains behind in the residue as the water evaporates and is collected as distillate.
