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.

Ions as Acids and Bases
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
