However, as we demonstrated, these various potential profiles differ qualitatively. In this section, we utilize the same simulation data to calculate the electric fields experienced by species in solution both in the bulk and at the electrode interface. By analyzing these calculations we can identify which potential profile, if any, is most consistent with the electric fields that act on electrolyte species. This section is organized similarly to the previous section. First, we analyze the average Madelung electric field profiles and compare them to the predictions of theory and simulation. Then, in the following subsection, we consider the electric field fluctuations and how they are affected by the presence of an interface.
