According to Nernst’s Distribution law (1891) or Partition law:
When a solute is taken up with two immiscible liquids, in both of which the solute is soluble, the solute distributes itself between the two liquids in such a way that the ratio of its concentration in the two liquid phases is constant at a given temperature provided the molecular state of the distributed solute is same in both the phases.
This is to mean :
C₁ / C₂ = Kd
Where C₁ and C₂ are the concentrations of the solute on two phases.
Kd is called distribution coefficient or Partition coefficient.
When a solute undergoes association, in one of the solvents we have :
Kd = C₁ / n√C₂
