The term is most often applied to liquids but also applies to solids and gases. An example in liquids is the miscibility of water and ethanol as they mix in all proportions. razer huntsman tournament edition green

"WitrynaIt is defined as the ratio between un-ionized drug distributed between the organic and aqueous layers at equilibrium. The partition coefficient of a drug may be determined by shaking it with equal parts of two immiscible solvents (the organic layer, which is saturated with water, and the aqueous drug solution) until equilibrium is attained.
