A chemical separation is a separation method that involves change in the chemical composition of one of the solutions that are to be separated in order to a new physical properties of one part reached leaving the rest alone.
For example, When we add a chemical to the solution that will precipitate only one part of the solution leaving the rest.
A physical separation is a separation in which solutions are separated on the basis of their physical properties.
For example, If we use physical separation method in separating two oils with different specific volumes then these two oils are separated on the basis of their settling.
