Water can be separated from salt through:
chromatography
distillation
evaporation
filtration
Water can be separated from salt through a process called distillation. In this process, the salty water is heated until it boils, and the steam is collected and cooled until it condenses back into water. The salt is left behind in the boiling container. This process can be used to purify salty water and make it safe to drink.
