Formula and explanation
Formula: K D = (c A)/(c B), where K D is the distribution coefficient, c A is the concentration of the solute in the extracting solvent (organic phase), and c B is the concentration of the solute in the original solvent (aqueous phase). Applicable conditions: Dilute solutions, constant temperature, the solute has the same molecular form in both phases. Description: Describes the ratio of concentrations of a solute distributed between two immiscible solvents at equilibrium, forming the theoretical basis for extraction separation.
