Redox potential
« on: January 16, 2016, 11:05:49 AM »
Hello everyone,

I wonder how I can measure the redox potential of Fe2+/Fe3+ in a mixture of acetonitrile/DMSO.
I need Pt wire, voltmeter and ref electrode but which reference should I use in organic solvents ?
Is a salt bridge necessary ?

Thank you for your help ! :)

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 !
