N2 - Chronoamperometry is reported on the one electron oxidation of 3 mM ferrocene in acetonitrile using a 300 (± 5 μm radius gold hemisphere electrode. Varying concentrations of supporting electrolyte (tetra- nbutylammonium perchlorate) are used ranging from the fully supported (100 mM) to the almost completely unsupported (0.1 mM). The response is simulated using the Nernst-Plank-Poisson system of equations and excellent agreement between theory and experiment noted, so vindicating a recent theory (J. Phys. Chem. C, 2008, 112, 13716) for voltammetry in weakly supported media.
