My question is related to electrochemistry. Let's suppose I have X material, and that material only shows an oxidation peak in any electrolyte, e.g., PBS, HCl, H2SO4, KOH, etc. In the case of the Ferro/Ferri solution, first I run the bare electrode, which shows a redox potential, and then I run the material-modified electrode in the Ferro/Ferri solution. In this case, does it increase the only oxidation peak or both?
