A molecular approach to electrolyte solutions: Phase behavior and activity coefficients for mixed-salt and multisolvent systems

摘要: Abstract A molecular formulation based on modern liquid state theory is applied to the properties and phase behavior of electrolyte systems involving volatile species. The goes beyond usual Debye-Huckel Pitzer correlations for treating concentrated solutions. optimized random resummation cluster diagrams as exemplified in EXP cation-cation, cation-anion, anion-anion distributions used ionic This represents an improvement over MSA approach. Electrolyte solutions such water-salt, ammonia-salt, mixed salts, mixed-solvent are investigated. salt properties, osmotic mean activity coefficients other thermodynamic calculated. predictions accurate saturation limits.
