Theory of the Differential Capacitance of the Double Layer in Unadsorbed Electrolytes

摘要: A partly phenomenological, one‐dimensional theory is presented of the double layer formed at an ideal polarized electrode in uni‐univalent aqueous electrolytes showing no specific adsorption. The system analyzed consists metallic with its surface charge density, a charge‐free next to electrode, and diffuse containing positive negative charges unequal concentration extending into body electrolyte. includes effect dielectric saturation both layers due field produced by applied bias potential, compression this also taken account.The compared experimental data D.

Good agreement found for dependence differential capacitance entire polarizing potential (measured from electrocapillary maximum) concentrati...
