Abstract
Activity coefficients are calculated for aqueous aluminum chloride and aluminum sulfate solutions at 298 K in terms of the generalized Debye–Hückel (DH) theory using experimental static dielectric permittivity versus concentration relationships. A semiquantitative fit of the experimental data is achieved; specifically, nonmonotonic activity coefficient versus concentration trends are reproduced. The applicability of the generalized Debye–Hückel theory to fit the thermodynamic properties of 3,1 and 3,2 valence type electrolytes is shown.
