Abstract

An expression is established to predict the Setchenow salting constants of solid and liquid organic compounds from aqueous solutions by electrolytes. It employs the conventional standard partial molar volumes and the intrinsic molar volumes of the ions. It also uses properties for the non-electrolytes that are foreign to their aqueous solution behavior: their molar volumes and either the Kamlet/Taft polarity/polarizability indexes or the Hildebrand solubility parameters. The expression is tested on data not included in the correlations used to establish it.
