In pharmacology, the partition coefficient (often expressed as Log P) helps scientists predict how easily a drug can cross cell membranes, which are primarily composed of lipids.
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 distribution law
The law is most accurate at low concentrations, where the solute behaves ideally. Practical Applications The law is most accurate at
If the distribution coefficient and the solubility of a solute in one solvent are known, its solubility in the second solvent can be calculated. Mathematically, this is expressed as:
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:
