The solute must not undergo association (clumping) or dissociation (breaking into ions) in either solvent. If the solute reacts with a solvent or ionizes, the formula must be modified to account for these chemical changes. Practical Applications
are the equilibrium concentrations of the solute in Solvent 1 and Solvent 2. KDcap K sub cap D is the Distribution Coefficient (or Partition Coefficient). Necessary Conditions and Limitations distribution law
The law is most accurate at low concentrations, where the solute behaves ideally. The solute must not undergo association (clumping) or
The law states that at a constant temperature, a solute will distribute itself between two immiscible liquids in such a way that the ratio of its concentrations in the two layers is constant, provided the solute exists in the same molecular state in both solvents. Mathematically, this is expressed as: KDcap K sub cap D is the Distribution
Solubility is temperature-dependent; therefore, KDcap K sub cap D only remains constant if the temperature is stable.
The two solvents must not dissolve in one another.
The Distribution Law is not merely a theoretical concept; it is the backbone of several industrial and laboratory processes:
