Abstract
The differential capacity of a large number of liquid-liquid interface s has been determined by impedance spectroscopy. Even in the absence o f ion pairing, the interfacial capacity was always larger than predict ed by Gouy-Chapman theory. These findings are explained within a simpl e model, in which an extended mixed-boundary layer exists at the inter face, whose thickness extends over several solvent diameters.
