Normally one of the two phases is an organic phase while the other is an aqueous phase. Under equilibrium conditions the distribution of solute i over the two phases is determined by the distribution law. After the extraction the two phases can be separated because of their immiscibility.Component i is then separated from the extract phase by a technique such as distillation and the solvent is regenerated.Further extractions may be carried out to remove more component i.Liquid liquid extraction can also be used to remove a component from an organic phase by adding an aqueous phase.
