Question

What do you mean by Fractional Distillation?

Answer 1

❖ Fractional Distillation :

❱ It is the process used for the separation of a mixture of two or more liquids that have different boiling points.

❱ Fractional distillation is carried out by using a fractionation column. In order to carry out the fractional distillation, we require a distillation flask, fractional column, Liebig condenser and a receiver.
