文摘A new expression for the osmotic and activity coefficients in single electrolyte solution is developed by reforming the Pitzer's osmotic equation.As a result,the correlations between the oMX,the sum of the"hard core"radii of ionsβ^(0)_(MX)andβ^(1)X_(MX),and the second virial coefficients/jjJx and'n Pitzer's equations are obtained.Furthermore,an"ionic overlap"model and its relevant equation are suggested.The relationships between the thermodynamic properties of aqueous electrolytes and the characteristic of their ions(ionic radii and ionic hydration)are discussed quantitatively.
