SEPARATION OF IMMISCIBLE
LIQUIDS BY SEPARATING FUNNEL
This is the instrument used to separate a mixture of immiscible liquids.
As the two liquids are separate layersit is easy to separate them.The method is…..
SEPERATING FUNNEL
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.
SEPERATION OF MISCIBLE LIQUIDS BY
DISTILLATION
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 56 𝑜𝐶and that of water is 100 . 𝑜𝐶
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 .
