Since the dielectric constant of KCl (without water) is way too low than dielectric constants of most of the ionic liquids is the charge migration from KCl to the ionic liquid feasible or do we have to consider the dielectric constant of water as KCl is already dissolved in water to form the salt bridge? What precautions we must take to minimize the potential drop between the reference electrode (RE) and the working electrode (WE) other than placing the RE closer to the WE? If KCl migrates into the IL system will chloride ion cause any possible erroneous results? Can someone please explain?
Whether the chloride ion will actually have an effect on your signal will depend on your potential window and what kind of data you are ultimately trying to collect.
But having said that, I don't think this system will be very stable and reproducible. Ag/AgCl isn't typically used as a reference electrode to study IL based systems. A metal wire (e.g. Pt) calibrated to the ferrocene redox couple would be better. Also, you typically want very little water in your system when you are doing work with ILs in a lot of cases (unless your specific research application requires it).
I suggest you review some related literature with procedures on IL electrochemical measurements. Good luck!
