Notes:
The structure of the hard sphere dipolar liquid and the electrolyte with added hard sphere ions near a charged hard planar electrode has been investigated with the reference hypernetted chain integral equation (RHNC). We find a decrease of the dielectric function ε near the wall, a decrease of ε in the fluid due to saturation, a field dependent change in the dipole density near the wall, and a decrease of the ion density near the electrode due to solvation. Related to the demixing instability of the ion-dipole mixture, the ions suddenly concentrate near the surface at higher fields and lead to a sharp increase in the differential capacitance. Also electrostriction in the pure dipolar liquid with a field in the bulk is considered. © 1995 American Institute of Physics.
