No, dear Michel Myures

No, is the short answer, e.g. it is not rational[1] to use Ag|Ag+ non-aqueous[2] RE (Reference Electrode) in CVs for common aqueous[3] solution(s).

However, describe, more, (or show link(s)) your RE for a(ny) possible[3], but always limited[4], very short total time, CVs, over and above, all common practice[1-4].

4. Why is there a frit in a Ag/AgCl reference electrode? https://www.researchgate.net/post/Why_is_there_a_frit_in_a_Ag_AgCl_reference_electrode

Yes, as a reference electrode. First, prepare standard buffer solutions (from borax, NaH2Po4, etc.) and after calculate the slope based on the Nernst equation . Sometimes, a glass electrode is included so that you can measure the pH of an aqueous solution (However, it is not always the case). For the measurement of the pH, the slope must be 59.

Yes[1], dear Michel Myures

I think that in your/this case, it might[2] work, at least, for low, better for very low[3], V-rate(s), Vr (Vr

When the stable Ag/AgCl reference electrode is used for non-aqueous systems, the electrolyte inside the Ag/AgCl reference electrode compartment (saturated KCl in water or a polar organic solvent) is often different than the main electrolyte (a salt in non-aqueous solvent). https://pineresearch.com/shop/kb/applications/general-electrochemistry/nonaqueous-reference-electrode-overview/

Good question

Thank you it is agood qustion
