Separation of miscible and immiscible liquids

A presentation about separating miscible liquids by separating funnel and separating immiscible liquids by distillation

1. Separation of immiscible Liquids by separating funnel

2. This is the instrument used to separate a mixture of immiscible liquids. As the two liquids are separate layers it is easy to separate them. The method is….. SEPERATING FUNNEL

3. Methods i . Pour the mixture into the funnel. ii. Let it stand undisturbed for sometime so that the layers get separated. iii. Open the stopcock of the separating funnel pour out the lower layer carefully. iv. Close the stopcock as the top layer reaches it.

4. SEPERATION OF MISCIBLE LIQUIDS BY DISTILLATION

5. Distillation . Distillation is a method of separating mixtures, based on differences in volatilities of components in a boiling liquid mixture. .Examples: acetone and water, ethanol and water. In acetone water mixture, the boiling point of acetone is 56𝑜𝐶 and that of water is 100𝑜𝐶.

6. Science behind distillation i . The low boiling liquid is evaporated first. ii. Its vapours are passed through the condenser and changed to pure liquid form. iii. This is collected in a beaker from the condenser outlet. iv. The other component is left in the flask in pure form .

7. Working of Distillation
