Simple Distillation

Simple Distillation – separation of pure liquid from a solution

by condensing vaporised liquid

Condensed pure liquid – distillate.

Distillation Process:

Solution is heated, and steam (pure vapour) is produced. The

steam is cooled in condenser to form pure liquid. Solute re-

mains in the flask.

Flotation method

This method is used to separate solid substances where one

floats on the other e.g. saw dust and sand.
