The anisotropic hypemetted chain approximation is applied to calculate the ion concentration profiles, the pair distribution functions and the surface-surface interaction between two uncharged slabs immersed in a primitive model electrolyte solution. The dielectric constant of the slabs is much smaller than that of the solvent. The full complexity of this problem is considered without further approximations. At short surface separations the ions are largely expelled from the space between the slabs due to repulsive image charge interactions. The pressure results clearly demonstrate the interdependence of the image charge interactions and the dispersion interactions between the slabs.

Density functional theories of solvation forces in charged fluids are extended to treat electrolytes consisting of finitesized ions and neutral solvent particles. The resulting forces display pronounced oscillations whose magnitude is a strong function of the bulk density of the neutral species.
The forces between two molecularly smooth mica surfaces were measured over a range of concentrations in aqueous Li -+, Na+, Kf and Cs\* chloride solutions. Deviations from DLVO forces in the form of additional short-range repulsive "hydration" forces were observed only above some critical bulk conce
