Question

1. How will you separate a mixture
containing kerosene and petrol
(difference in their boiling points
is more than 25°C), which are
miscible with each other?
​

Answer 1

Answer:

Distillation

Explanation:

Simple distillation can be used when the temperature difference between the boiling points of two miscible liquid is at least 25oC. The temperature difference between the boiling points of kerosene and petrol is 25oC. Hence, this mixture can be separated using simple distillation.

Answer 2

Answer:

fractional distillation

Explanation:

both liquids are mixed and are boiled. less boiling point liquid will start evaporating and will condense in leibigs condenser and fractional column will seperate vapours of both liquids and less boiling point liquid will be collected in another flask.
