Question

How will you separate a mixture containing kerosene and petrol (difference in their boiling points is more than ${25}^{0}C),$ which are miscible with each other?

Answer 1

The mixture of kerosene and petrol which are miscible with each other can be separated by distillation.

The mixture in a distillation flask and fit it with a thermometer. On heating the mixture slowly, we will observe that petrol vaporises first as it has a lower boiling point. It condenses in the condenser and is collected from the condenser outlet. Kerosene is left behind in the distillation flask.
