Ion Interaction parameters for 304 single salts In aqueous solution have been obtained lor PHzer's equations. For most of the cases we evaluated, the range of molality extended up to saturation when data were available. The calculated activity coefficients of HCI, LIBr, CaBr2, Pr(N03)3, and MgS04 from our results and Pltzer's were compared to available smoothed experimental data. The comparisons show better agreement with experimental data when we use values of our parameters which were evaluated at higher concentrations than those used by Pitzer.
