    Distribution law was given by :

    A) Ostwald

    B) van't Hoff

    C) Nernst

    D) Henry

    Correct Answer: C

    Solution :

    Distribution law was given by Nernst. He found that if a substance is present in different phases (say liquids) in a system at equilibrium then the solute distributes itself between two immiscible solvent in contact with each other in such a way that at constant temperature the ratio of its concentration in the two liquids is constant, whatever the total amount may be. It is known as distribution law. If \[{{C}_{1}}\]and \[{{C}_{2}}\]represent the concentration of a solute in the two solvents then \[\frac{{{C}_{1}}}{{{C}_{2}}}=\] constant = K where K is distribution or partition coefficient
