Neutral SpeciesNeutral molecules in water are affected by other species in a solution. The salting in and out of a gas is a typical example. When oxygen is dissolved in pure water, it has a typical solubility. When salt is added, the oxygen solubility decreases.
This is most likely due to interactions of sodium and chloride ions reacting with the neutral oxygen molecule.
B.8 Mixed Solvent ModelThe model1 is developed to handle electrolyte systems ranging from infinite dilution to solid saturation or pure solute limit and for various completely miscible inorganic systems over a full concentration range.
Also, the model is capable of representing phase equilibria in multicomponent inorganic systems containg multiple salts, acids, and bases. Complex phase behavior such as formation of multiple hydrated salts, double salts, or the presence of eutectic points can be accurately represented. The model is equally valid for classical aqueous systems, those with more than one distinct solvent and mixtures in whihc a given component may continuously vary from being a solute to being a solvent.
