Solution
A Solid component is separated in a soluble solid-liquid mixture by evaporation.
Principle — Separation of the mixture by evaporating the liquid component. The solid should be soluble in the liquid and should not sublime.
The technique of Separation: The soluble solid can be separated from its liquid component by allowing the liquid component to evaporate either on its own or by heating. During evaporation, the liquid component is lost to the atmosphere & the solid remains behind.
Example: Evaporation of a common salt solution or seawater leaves behind common salt. Common salt remains behind whereas water lost to the atmosphere.
