this video exemplify what i was talking recently..
when we submerge a metal its free electrons will be attracted to the water molecules because they are free to move and this makes the electrode positive in some sense
the higher is the atraction of the metal to its electrons the lower will be the potential
both electrodes therefore have some sort of negative electric field on the surface.... to revert this electric field electrons must be taken off from the electrode making it now positive.. so in an electrolysis when we add charge o it the negative electrode will be more negative than the positive electrode in relation to the water solution
i´m planing on using potassium nitrate
my idea is that it will form a basic electrolyte near the positive electrode and acid near the negative electrode due to the proximity of the respective opposite ions. i even thought about adding some potassium to bring it to elevate the ph or acid to lower the ph...
