So, if I am understanding this correctly, the more positive the ORP is,
the more oxidative it is. Thus the drop in the ORP would indicate that
something that was oxidative (silver oxide) has been reduced (now silver
metal). Unless I am misinterpreting, that is what I would expect.
However if all the silver was reduced though, the question for me is,
what is still there that is oxidizing, that is why is the ORP not 0?

Hello Marshall,
Oxygen reduction potential (ORP) is measured using equipment similar to that
used to measure PH. The probe is constructed differently from the PH probe,
but the measurement process is similar.
Here is an introductory article on ORP.

My interest in ORP comes from exploring the concept of using EIS to
disinfect raw water for drinking, and to explore its use to disinfect waste
water for emergency sanitation in the event of a natural (or unnatural)
disaster.

Hello Marshall,
Another interesting observation...
The oxidation reduction potential of my EIS is around 0.550 mV. The
solution that I added the ascorbic acid to comes in at around 0.186 mV.
I
don't know if this is significant, but it is interesting.
Can you elaborate on this? How do you do the measurement?
