On the application of the associative mean spherical approximation to the ion-dipole model for electrolyte solutions

Abstract The solution of the associative mean spherical approximation for the ion-dipole model of an electrolyte solution is simplified and analyzed. It is shown that the description of this model can be reduced to a system of three coupled non-linear algebraic equations for ion-ion, ion-dipole and dipole-dipole energy parameters J 0 , b 1 0 and b 2 . A possibility of introducing ionic and dipolar scaling parameters Γ B and λ is discussed. Analytical expressions for the thermodynamic functions and solvent static dielectric permittivity are presented.
