Summary of the charge reductions produced by the reductions of internal or external ionic strength (S). The planar expectation is the reduction of potential for the indicated value of S calculated with Formula 7 for a given pair of values of S as Δf(318) − Δf(S) for the internal effects of S; and as Δφ(325) − Δφ(S) for the external effects, where Δf = φ_{a}- φ_{e}. Here φ_{a} and φ_{e} are the potential at the apex of the internal cavity and at the base of the external cavity, respectively. The values of the reduction are the mean ± SEM The value n is the number of experiments.
