Potential difference across a double layer containing an asymmetric electrolyte in the mean spherical approximation
Abstract
Analytic expressions, obtained from the mean spherical approximation, for the double-layer potential difference and density profile contact values at the electrode are given for a general electrolyte containing an arbitrary number of components whose diameter and charge are unrestricted. These results are exact, within the mean spherical approximation. A low-concentration expression for the mean spherical approximation density profiles is also given for the general electrolyte. Because of the limitations inherent in the mean spherical approximation, these results are applicable only near the potential of zero charge. However, this is the region where the effects of asymmetries are most apparent. © 1984 American Chemical Society.
