Solution
By Distillation
Principle- Based on the distillation of the liquid component in a soluble solid-liquid mixture.
Distillation – It is the process of converting a liquid into vapour by heating in a distillation flask & subsequent condensation of the vapour back into the liquid.
The method is used to separate a liquid from a soluble solid or pure liquid [water] from impure liquid [impure water].
The technique of Separation The soluble solid can be separated from its liquid component or pure water from impure water by placing the mixture i.e. impure water in the distillation flask.
On heating the distillation flask
The solid or solid impurities in the water remain behind in the distillation flask
The liquid or water vaporizes, condenses in the Liebig’s condenser, and is collected in the receiver.
