TL;DR: In this paper, it was shown that the weak specific adsorption of ions not involving the recharging of the electrode surface is characterized by the following unusual features: practical absence of any shift of p.z.c., a very small discrepancy between the experimental differential capacity curves and similar curves calculated under the assumption that specific adaption is absent (q1 = 0), insensitivity of the total surface excess of cations to their distribution between the dense and diffuse layers, practical independence of q1 of temperature and the bulk concentration of binary electrolyte; practical coincidence of c

TL;DR: In this article, the steady-state voltammetric behavior for the oxidation of aqueous solutions containing the strong bases sodium and barium hydroxide was studied with gold microelectrodes in the absence and in the presence of different concentrations of supporting electrolyte.
Abstract: The steady-state voltammetric behavior for the oxidation of aqueous solutions containing the strong bases sodium and barium hydroxide was studied with gold microelectrodes in the absence and in the presence of different concentrations of supporting electrolyte. A well-defined oxidation wave attributed to the oxidation of hydroxide ions to oxygen was observed in all the solutions investigated, regardless of both the nature of the base and the supporting electrolyte employed. However, in solutions with excess electrolyte, the steady-state limiting current was found to depend on the actual concentration of the supporting electrolyte, as the diffusion coefficient of the electroactive species varies with both the ionic strength and viscosity of the medium. Since the hydroxide ion is a negatively charged species, solutions with low or without supporting electrolyte yielded currents enhanced by migration contributions. Theoretical equations for the dependence of steady-state limiting currents with ionic strength...

TL;DR: In this paper, the ionic liquid, IL, dependence of the mid-point potential of the ferrocene,ferrocenium, Fc0/+, couple versus the decamethylferrocene|decamethy lecnorrocen, DmFc 0/+ couple was studied in eleven ILs and in dichloromethane with added IL as the supporting electrolyte, and a variable potential shift ranging from 0.014 to 0.082 V was observed when data was compared in these two systems.
