Question #79178
The ratio of the concentration of the solute in each solvent at equilibrium is a constant called
Expert's answer
The ratio of the concentration of the solute in each solvent at equilibrium is a constant called a partition-coefficient (P) or distribution-coefficient (D).
This ratio is therefore a measure of the difference in solubility of the compound in these two phases. The partition-coefficient generally refers to the concentration ratio of un-ionized species of compound whereas the distribution-coefficient refers to the concentration ratio of all species of the compound (ionized plus un-ionized).
