Partial molar volumes of aqueous 1:1 and 2:1 electrolytes and a structure model

An expression for partial molar volumes is derived from the free energy equation based on field-dielectric-gradient forces, as well as coulombic forces, between ions in structured solution. Qualitative agreement between the model and experimental partial molar volume data is very good. Excellent qua...

Description
Summary:An expression for partial molar volumes is derived from the free energy equation based on field-dielectric-gradient forces, as well as coulombic forces, between ions in structured solution. Qualitative agreement between the model and experimental partial molar volume data is very good. Excellent quantitative agreement is obtained by adopting for a universal parameter of the theory a value that implies for water at 25 °C and 1 atm. The latter value is compatible with data obtained from direct measurements.
