4. 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

6. 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.

7. 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 .
