Stoichiometry
In case of a ternery system involving two liquid components and a solute, the ratio of the concentration of the solute in the two phases at equilibrium is called the distribution co-efficient. The distribution co-efficient depends upon the
Sizes of the component molecules are approximately equal
Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
Attractive forces between like and unlike molecules are approximately equal
