Abstract
Electrocapillary curves at the polarized interface between a nitrobenzene solution of tetrabutylammonium tetraphenylborate (TBATPB) and an aqueous solution of lithium chloride at various concentrations of TBATPB and LiCl have been measured by the drop time method using a dropping electrolyte solution electrode at 25 °C. The relative surface excesses of tetrabutylammonium and tetraphenylborate ions in the nitrobenzene phase and of lithium and chloride ions in the aqueous phase were well described by the Gouy-Chapman theory of diffuse layers for both sides of the interface. A model of the electrical double layer for the nitrobenzene–water interface is presented, in which an ion-free inner layer consisting of laminated monolayers of water and nitrobenzene is sandwiched by the two diffuse layers on each side of the interface. The potential difference across the inner layer, which was estimated to be ca. 20 mV at the potential of zero charge, was found to be dependent on the surface charge density and to be ne...
