Abstract
When an aqueous solution of succinic acid is shaken with ether, the acid distributes itself between the ether and the water in such a way that the ratio between the two concentrations is always constant. It will be seen that the distribution of succinic acid between two solvents is analogous to that of a substance between the liquid and gaseous phases, and therefore, the laws governing the latter equilibrium should apply equally to the former. (1) Nernst has shown that (a). If the molecular weight of the solute is the same in both solvents, the ratio in which it distributes itself between them is constant, at a constant temperature, or, in other words, Henry's law Is applicable; and (b). If there are several solutes in solution, the distribution of each solute Is the same as if it were present alone. This is clearly Dalton's law of partial pressures. The ratio in which the solute distributes itself between the two solvents is termed the coefficient of distribution. When the molecular weight of a solute is not the same in both solvents, the distribution coefficient is not constant, and conversely, if the distribution coefficient is not constant, it is inferred that the solute in the two solvents is not identical.
