Question:

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

Answer:

Simple distillation separation technique We separate the two miscible liquids on the basis of their boiling point. Boiling point of petrol is lower than kerosene which will distill first in the form of vapours and will be collected in a separate beaker.

Kerosene having higher boiling point will distil later on and will be collected in another beaker.
