Of course, I'm sorry !
About the electrode I found the "non-aqueous Silver/Silver Ion (Ag/Ag+)" but is that common or do you have others suggestions ?
In my solution I have water/toluene/acetonitrile and iron salt (but there is a great homogenization with acetonitrile) so I wonder, which is the "real potential" of Fe2+ / Fe3+ in my case considering that I have 2 phases at the end ?
Because the iron salt is in both phases so I don't think I can only consider one phase...
Thank you !
