KARPEN PILE

[pomodoro]

My prediction of this karpen oxygen cell is that there will be no voltage difference at all between the dissimilar electrodes when I disconnect the short in hours time . Karpen and Profitis would probably disagree.   

This is an ultra easy experiment almost anyone can do, the electrodes are very inert, the only redox couple existing in equilibrium is 2H2O<-> 4H+  + O2   +4e-. This will have the highest current density on  both electrodes. There is no hydrogen, so the other water redox reaction has no influence.  Its happening on both electodes, oxygen pressure is constant, proton concentration is constant, The kinetics or rate may be different, but the potential by nernst is the same.

Please comment on this, anyone is welcome, before I video tape the event.

Saying that there will be no potential difference after long rest is like saying that there is no potential difference between Pt and carbon pomodoro.let them rest for one hour after disconnection.

So you are saying that after letting them for a few hours after the short is removed, you expect a potential difference to develop? Lets be clear about this Profitis,  people need to understand exactly what we are doing and mean by our words.  Thats why I've stated as clearly as possible what I have done in this experiment  There is no conspiracy at work here,  anyone interested needs to replicate these tests for themselves.  Not too hard when just air is needed.

Of course pomodoro.do you think that a anodized carbon rod retains oxygen gas indefinitely? Impossible.the gas diffuses away,electrolyte wets surface.atomic O recombines into O2 and diffuses to where the pressure is alleviated.Its very small v anyway its not importante.leave it for an hour before measurement.
