title: Salting coefficients of carboxylic acids in various saline media.
abstract: Reported partition coefficients and solubility data at 25 degrees C were used to determine the salting coefficients of acetic, benzoic, o-chlorobenzoic, m-chlorobenzoic, p-chlorobenzoic, o-hydroxybenzoic, m-hydroxybenzoic and p-hydroxybenzoic acids in various saline media. Coefficients were calculated on the molarity and molality scales. Except for acetic acid, which exhibited a negative coefficient in two of the 29 electrolytes used, all the acids were found to have positive values in the studied media. Consequently, the presence of a salt decreases the solubility of these acids.
