electrochemical cell
« on: September 08, 2011, 11:27:16 AM »


I have an electrolyte solution ( kcl) in electrochemical cell the electrodes are made of silver. I want to calculate the minimum potential difference to start the electrolysis reaction.

My purpose is to prevent these reaction form happening, I want to my electrolytes solution to be conductive, so electrolysis is not favorable.

any word on this subject will be helpful

Thanks

An electrolyte is any medium which conducts electricity by ionic means.
Current-transfer by ionic means is electrolysis.

Its a little hard to understand your application, amal:, but it appears you need a conductive solution that won't decompose.  We use such solutions to manufacture electrolytic capacitors.  Maybe the solutions used in them will suit your application?

That's a lousy wording.

Current in the bulk of the solution doesn't require electrolysis. However, you need an electrode reaction to move the charge through the phase boundary.
