Abstract:

The purpose of this work was to develop a dynamic partial order model of electrolyte solutions which avoids inconsistencies present in the Debye-Huckel and in related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work are a partial long-range order which increases with concentration due to the increase in the coulombic energy of interaction and decreases with temperature, a contribution from ionic fluctuations because it is shown that displacements from average positions lead to a symmetric increase in energy which is not cancelled out, and a hydration correction for the effect of hydration upon the effective ionic concentrations. Ions are given partial counter-ion character as a function of the degree of order so that the free energy of ionic interactions can be calculated rigorously, as if the lattice were perfect, without resort to cluster integrals in the case of single salt solutions.
