Water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container. The salt does not evaporate and so it stays behind.

Separating Salt from Water
Separating salt from water can be achieved through various methods. Here are three common methods:

Boiling
- Boiling is a simple and effective method to separate salt from water. When water containing salt is boiled, the water evaporates, leaving the salt behind.
- The steam produced during boiling can be collected and condensed back into liquid water, leaving the salt as a residue in the original container.

Filtration
- Filtration is another method to separate salt from water. In this process, a filter such as a piece of cloth or filter paper is used to separate the salt from the water.
- The salt particles are too large to pass through the filter, so they are trapped while the water passes through, leaving the salt behind.

Decantation
- Decantation is a process in which the saltwater mixture is allowed to stand undisturbed until the salt settles at the bottom of the container.
- Once the salt has settled, the water can be carefully poured off, leaving the salt behind.
In conclusion, all three methods - boiling, filtration, and decantation - can be used to separate salt from water. The choice of method depends on the specific situation and the equipment available.
