S. No. Separation by distillation Separation by separating funnel
1. This method is employed for the separation of
two miscible liquids.
This method is employed for the separation of two immiscible liquids.
2. It is based on the difference in the boiling points of two liquids. It is based on the difference in the densities of the two liquids.
