Salt water contains two different pure substances, water and sodium chloride. Because these substances are not bonded together they can be separated by evaporation. The water evaporates and leaves salt crystals behind.
Desalinating sea water is commercially and practically accomplished by osmosis, where the sea water is forced through a very fine membrane, as a way to provide drinking water where only sea water is available.
On a small scale:
Distillation:
Heat the salty water and condense the water vapour back into water. This will leave the salt crystals behind.
Distillation is the most common way to get pure water from salt water. Note that more exotic techniques can also be used, such as reverse osmosis. In distillation, the water is boiled, and the water vapor is collected. The vapor is condensed to produce fresh water, whereas the salt is left behind in the boiling vessel.
In reverse osmosis, the salt water is pumped through a semipermeable membrane, which only allows the water to pass through, not the salt. Pure water crosses the membrane, whereas the salt impurities are left behind. Note that osmosis normally operates in the opposite direction, and thus this process must be forced with tremendous pressures, requiring a great deal of energy.
Usually destillation or filtration.

∙ 14y agoyou can evaporate it by putting salt water ina bowl and leaving for a couple of days
6-7 you can also strain it or boil it

Why does salt separated from a salt water look different than the salt that dissolved in the water?
The separated salt is a crystalline solid; the dissolved salt is dissociated in ions.
Who can salt be separated from water?
Salt can get separated from saltwater by putting it into a pot or in the sun and boiling it which will cause the water to evaporate and the salt will be left there.
Why does salt separated from salt water solution look different than the salt that dissolved in the water?
The separated salt is a crystalline solid; the dissolved salt is dissociated in ions.

What is a clear liquid which can be separated into water and salt by distillation?
salt water
Can be separated the salt?
Sodium chloride can be separated from water by water evaporation or by distillation.
What substances can be separated by chemical means salt water water gold?
salt water
How does salt water can be drinkable?
Salt water is not drinkable: the salt must be separated by evaporation, distillation, etc..
How you could use water to separate salt?
Evaporate water, then the salt would be separated.
Salt water can be separated by evaporation?
Yes. You can separate water from a salt solution by evaporation.
Salt dissolved in water can be separated by?
