Salting coefficients of carboxylic acids in various saline media

Reported partition coefficients and solubility data at 25 degreesC were use d 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 calculate d on the molarity and molality scales. Except for acetic acid, which exhibi ted a negative coefficient in two of the 29 electrolytes used, all the acid s were found to have positive values in the studied media. Consequently, th e presence of a salt decreases the solubility of these acids.
