Ion exchange in a heterogeneous system. Solvent extraction

A solvent extraction system consists of two liquids insoluble in each other. The organic ligand (R) is water-insoluble.

Preference of the ligand to sodium ion or to potassium ion can be altered moving the slider attached to the applet.

Preference to one ion causes accumulation of this ion in the oil phase.

For simplicity, charge-compensating anions present in the aqueous phase are not shown.
