“…The MP approach permits determination of various binary and ternary interactions consisting of nonelectrolyte–ion and nonelectrolyte–nonelectrolyte–ion coefficients. Meanwhile, it seems that the MP equation gives better results when the nonelectrolyte species are not assumed as the solvent. ,, Figures and present the behavior of the correlated data at the range of concentration to demonstrate the ability of different models.…”

This study is conducted to investigate the HCl + NaCl + H2O + C2H5OH mixed electrolyte systems. The experimental activity coefficients are collected through measuring the electromotive force by using a cell containing pH and silver chloride electrodes in different alcohol mass fractions w(C2H5OH) in H2O (where w = 0.10, 0.20, and 0.50). All the used electrolyte molalities are between 0.01 and 2.5 mol kg–1, at 298.15 ± 0.01 K. Modeling is achieved using mean activity coefficients data for single and mixed HCl and NaCl in mixed solvent. A detailed study of Pitzer’s equations regarding effectiveness of nonionic species is taken into account. The result shows that this approach is a valuable aspect of the Pitzer equation for activity coefficient correlation of pure and mixed electrolytes, in mixed solvent media. The result underlines the importance of including Friedman’s higher-order limiting law (HOLL) regarding fitting the activity coefficient data for symmetric mixture, that is, not only theoretically accurate but also practically important. It seems that this work would be considered as the first experimental observation for the HOLL to correlate the activity coefficient of symmetrical mixture.

Thermodynamic properties of K 2 HPO 4 /D-sucrose/water ternary solutions were investigated at 298.15 K. Water activity, osmotic coefficient, and electrolyte saturation points are determined by measuring relative humidities in the wide range of K 2 HPO 4 molality (ranging from 0.1 to approximately 5 mol•kg −1 ) and for various D-sucrose contents (0.1, 0.3, 0.5, 1, 2, 3, 4, 5, and 5.5 mol•kg −1 ) in the ternary K 2 HPO 4 /D-sucrose/water system. The solid state was characterized using powder X-ray diffraction (XRD) and attenuated total reflection Fourier-transform infrared (ATR-FTIR) techniques. The obtained data were then analyzed using the Pitzer-Simonson-Clegg (PSC) model to determine several thermodynamic properties. These properties encompass the stoichiometric ionic mean activity coefficient of K 2 HPO 4 , excess Gibbs energy, solubility in aqueous solutions, and the Gibbs energy of transfer of K 2 HPO 4 between water (W) and D-sucrose/water (W+S) mixtures. Furthermore, the interactions among water, D-sucrose, and K 2 HPO 4 are also examined and discussed.
