Why ions are not detectable on a bare electrode?

01 February 2024 1 301 Report

Why metal ions with high half potential can't be detected on a bare electrode even though corrosion doesn't happen and I'm using the suitable carbon working electrode and Ag/AgCl for the reference electrode and the right setting and range?

If you place a metal (electrode) in an aqueous solution, then at the boundary of the electrode and the aqueous solution there is an equilibrium:

Metal on electrode < > metal ions in solution. Therefore, there are no metal ions on the electrode.
