It is the simplest and most widely used method. The method is to be applied when the distribution D is high.

Requirement: Simple glass separating flask beaker, funnel etc.

Experiment: In this technique the aqueous phase containing the solute to be extracted is brought in contact with the immiscible organic solvent in a simple separating funnel. The two phases are shaken vigorously at least for 10-15 minutes. Then are allowed to attain the equilibrium. After the layers become clear, the denser liquid is withdrawn by opening the stop cock of the funnel. Once the denser liquid is separated, then lighter layer is separated.
