Question

What are limitations of distribution law

Answer 1

Distribution law or the Nernst's distribution law[1] gives a generalisation which governs the distribution of a solute between two non miscible solvents.This law was first given by Nernst who studied the distribution of several solutes between different appropriate pairs of solvents.

Where Kd is called the distribution coefficientor the partition coefficient.

If C1 denotes the concentration of solute X in solvent A & C2, the concentration of X in B; Nernst's distribution law can be expressed as
