Abstract
Drops of nitrobenzene and 1,2-dichloroethane with 0.1 M decamethylferrocene (dmfc) are attached to the surface of a paraffin-impregnated graphite electrode and immersed into various aqueous electrolytes. The oxidation of dmfc and the reduction of dmfc+ cation are enabled by simultaneous transfers of anions between the aqueous electrolyte and the organic solvents. Square-wave voltammetry of this reaction is reported. A linear relationship was observed between the peak potentials of dmfc and the standard Galvani potential differences of the anions. The influence of the anion concentration on this relation is explained.
