- Аннотация: Electrocapillary curves recorded at a Hg electrode in aqueous KBr solutions were used to calculate the adsorption capacitance C(ads) and high-frequency limiting capacitance C(infinity) as functions of charge q, as well as the frequency dependence of measured capacitance C(s) and resistance R(s) arising from the effect of diffusion of salt molecules on the current redistribution between capacitances C(infinity) and C(ads). The results were compared with analogous data that had been obtained previously for ideally polarizable electrodes in solutions of surface-inactive electrolyte. In contrast to the latter situation, the capacitance ratio C(ads)/C(infinity) can become positive. It was found that the specific adsorption of anions gives rise to stronger capacitance dispersion at q > 0 and to more negative values of the charge q* at which C(s) and R(s) are independent of ac frequency.
