Abstract:
The analytical solution of the Mean Spherical Approximation for the case of equal size ions and different size solvent is reexamined using only two parameters a polarization parameter lambda and a screening parameter Gamma. We show that the ion dipole cross energy parameter, which in previous work was obtained solving a cubic equation, can be obtained from a linear algebraic equation. Therefore, the inverse problem of calculating the reduced charge parameter d sub 0 and the reduced dipole parameter d sub 2 from lambda and Gamma is reduced to a system of two equations a cubic for d sub 0, and a linear for d sub 2. Simpler expressions for the thermodynamic parameters are also obtained.
