• Separation by distillation Implies a difference in boiling points of two or more materials. We separate many things by detecting a difference in a physical properties

PRINCIPLE OF DISTILLATION:

The basic principle of distillation is simple

• When a solution of two or more components is boiled

• The lighter component (the one most volatile or the one with the greatest tendency to vaporize )vaporizes preferentially

• Two component mixture is contained in a vessel

• When heat is added until the more volatile material ( red dotes ) start to vaporize. Now the vapor contains a higher proportion of red dots than dose the original liquid

• It is important to note that an equilibrium in composition will be established at a given temperature and pressure. 

• By equilibrium we mean there is a given concentration as “red dots" in the vapor and in the liquid depending upon the original concentration of each component in the liquid and their respective properties in relation to each other
