“…Measuring and modeling for electrolyte behavior in aqueous and nonaqueous media is necessary because of the need to investigate the nature of various industrial and environmental processes. Despite the successful achievements of mixed electrolyte studies in aqueous media, investigations in nonaqueous or in mixed solvent media are still very limited. − Among the proposed equations, the Pitzer model and the Harned rule seemed to be the most favored ones among the published works. Typically some of the literature used the Harned rule, − while the others implemented the Pitzer formalism. − …”

The emf of the cell is measured to investigate the HCl + NaCl + H2O + CH3OH mixed electrolyte systems. The experimental data are obtained over the electrolyte molality ranging from 0.005 mol kg–1 up to about 3.5 mol kg–1, at 298.15 ± 0.01 K, by using a cell containing a pH and a silver chloride electrode in different alcohol mass fractions x(CH3OH) in H2O (where x = 0.10, 0.20, 0.30, 0.40, and 0.50). The mean activity coefficients of HCl in the mixtures are computed. Modeling is implemented by the classical Pitzer (CP) equation and original Pitzer (OP) equation that are included by the additional terms which are arising from interactions of neutral species and finally the modified Pitzer equation by Merida et al. (MP). The different aspects of proper parameter choosing in fitting processes especially for pure and mixed electrolytes in mixed solvent systems are signified in the results.

Standard electrode potentials E o of Ag-AgC1 electrode in molality scale and a c i d i e constants of glycine PEP at constant molality of NaCl (1.0 mol-kg-1) in 5 and 15 mass% glucose-water mixed solvents over a range of temperature8 from 278.15 t o 318.15 K were. determined from precise emf measurements. The dependence of acidity constant on temperature i n given as a function of the thermodynamic temperature T by an empirical equation. p K ; = d l ( K / T ) -d z + d~( T / K ) . The corresponding thermodynamic quantities of the f i r s t dissociation procese of plycine were calculated and the effects of both the solveiit and the salt on them were also discussed. 12.
