How will you separate a mixture containing kerosene and petrol (difference in their boiling point is less than 25 K) which are miscible with each other ? Explain.

Explanation

Both are miscible liquids. Since the difference in the boiling points is less than 25 K, the separation can be done with the help of fractional distillation technique. Petrol with less boiling point distils first leaving behind kerosene in the distillation from flask. However, it is very difficult to apply this technique since both are highly flammable liquids and a great deal of precaution is needed. For the details of fractional distillation.
