On the Helmholtz Free-Energy of Highly-Charged Plates in an Electrolyte - Reply to the Criticisms
It is shown that the treatment of the interaction of electric double layers given by Sogami, Shinohara, and Smalley is a rigorous solution to the one-dimensional colloid problem. In one criticism Levine and Hall have claimed that whereas our expression for the adiabatic pair potential is correct, our force expression is incorrect. It is shown that their method contains both a conceptual error and a mathematical mistake. In another criticism Ettelaie has claimed that we missed a chemical term in our treatment of the problem, by failing to satisfy the Nernst equation. His argument is answered by demonstrating that including the term which he claims has to be added to the SSS adiabatic pair potential leads to the system not being at thermal equilibrium. That including the extra term leads the SSS potential back to the DLVO potential shows that the DLVO theory imposes an unphysical Nernstian behavior on colloidal systems.
