N2 - The restricted primitive model of an electrical double layer around a spherical macroparticle was discussed. The theoretical curves for the Helmholtz and surface potentials versus the macroparticle charge showed an unexpected positive curvature when the ionic size of uni- and divalent electrolyte species was increased. The concept of compactness of the electrical double layer was introduced. Analysis shows that the interplay between electrostatic and ionic size correlation effects was responsible for the singularity.
