The application of the pitzer equations to 1-1 electrolytes in mixed solvents

Thermodynamics of the cell: {NaxHg1−x|NaCl(m)|AgCl|Ag} in (methanol+water) solvent mixtures

“…DE were measured by Feakins and Voice (15) to obtain molar Gibbs energies of NaCl transfer from water to (methanol + water). Such DEs with related DE°ms were also processed by Koh et al (17) using Pitzer's theory of activity coefficients. The early measurements on type (V) cells by A kerlo¨f (18) have been criticized (15,17) and found to be unsuitable for extrapolation to the standard state.…”

Experimental measurement and modelling of KBr solubility in water, methanol, ethanol, and its binary mixed solvents at different temperatures

“…Similarly to Koh et al (37) Chen and Evans, (38) and Achard et al (39) in this work, the differentiation of the parameter A D H,x which is solvent composition dependent through the density and the dielectric constant of the solvent has been neglected. The values of that parameter are, however, evaluated as a function of the solvent composition.…”

Thermodynamic properties of multicomponent electrolyte solutions in mixed solvents. 5• HCl + NaCl + urea + water at 278.5–318.15 K

“…According to Khoo's suggestion (12), a = 2, b = 1.2 in mixed solvents. Then, the Nemst equation reduces to where k' = RT/F and mo = 1 mol kg-'.…”

“…The relevant equations for a 1-1 single electrolyte solution derived by Pitzer are where each symbol has the same meaning as in Pitzer's article (12,13). Since the molality of HCl used in the experiment is so dilute, CMX may be recognized as zero.…”
