Solvent effect on the partial molar volume and the enthalpy of solution of gallium chloride

Abstract

Partial molar volumes and heats of solution were determined for gallium chloride in benzene, toluene, o-xylene, mesitylene, 1,2-dichloroethane, ethyl acetate, acetonitrile, and 1,4-dioxane. A proportionality in changes in these characteristics is observed for weak π,ν-type complexes in alkylbenzene medium. The partial molar volumes of strong n,ν-type complexes approach a limiting value.
