If in a system of two immiscible or slightly miscible solvent, a substance, soluble in both the solvents is added, then the added substance will distribute itself between the two liquids in a definite manner depending upon its solubility. At equilibrium the ratio of the concentrations of the solute in the two liquids is constant at a given temperature and is called the distribution coefficient or partition coefficient. It is important that the solute must exist in the two solvents in the same molecular state.

Distribution of iodine between two immiscible solvents
In the physical sciences , a partition coefficient P or distribution coefficient D is the ratio of concentrations of a compound in a mixture of two immiscible solvents at equilibrium. This ratio is therefore a comparison of the solubilities of the solute in these two liquids. 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. In the chemical and pharmaceutical sciences , both phases usually are solvents. Partition coefficients are useful in estimating the distribution of drugs within the body. Hydrophobic drugs with high octanol-water partition coefficients are mainly distributed to hydrophobic areas such as lipid bilayers of cells. Partition coefficients can be measured experimentally in various ways by shake-flask, HPLC , etc.
Volatilization: a soil degassing coefficient for iodine. Iodine , an element essential to some animals, is ubiquitous in the biosphere. Unlike other metallic elements, molecular I is volatile, and other inorganic species present in aerated soils, such as I - and IO 3 - , may also volatilize as hydrides, hydrogen iodide HI , or hydrogen iodates HIO 3 , HIO 4. Methyl iodide has been measured in soils, and it is likely evolved from soils and plants. The long-lived radioisotope I is abundant in nuclear wastes, and its high solubility in groundwater makes it an important element in the performance assessment of underground disposal facilities. Overestimates of soil I residence half-times by traditional foodchain models may be due to underestimation of volatilization.
This page describes the phenomena of a solute dissolving in two immiscible liquids in contact with one another — known as a partition equilibrium. Simple calculations are described using an equilibrium expression and the partition coefficient. The theory behind multiple partition using a separating funnel is also described and explained. Part 4 sub—index 4. Advanced Equilibrium Chemistry Notes Part 1. The word ' partition ' means a substance X is distributed between two phases in a dynamic equilibrium. It is a heterogeneous equilibrium since the 'solute' is distributed between two distinct phases.
4.5: Extraction Theory
When a solute is shaken with 2 immiscible solvents it gets partitioned between the solvents. This distribution of solute in 2 solvents depends upon the solubility of the solute in two solvents. At the distribution equilibrium, the ratio of concentrations of solute in both solvents is constant at a given temperature. The constant is called the partition coefficient K or the distribution coefficient of the solute between the two solvents. Aim: To establish the partition co-efficient of iodine in distilled water d.

Сначала изображение на экране было смутным, точно смазанным сильным снегопадом, но постепенно оно становилось все четче и четче. Это была цифровая мультимедийная трансляция - всего пять кадров в секунду. На экране появились двое мужчин: один бледный, коротко стриженный, другой - светловолосый, с типично американской внешностью. Они сидели перед камерой наподобие телеведущих, ожидающих момента выхода в эфир.
