Not true, the rest potential of silver in alkaline solution in a hydrogen atmosphere was found to be only 4.6mv different to a pt   in the same solution.

It looks like I will have to put up a demo myself

Attempting to back your own claims has always been a good idea.

Pomodoro,I'm going to ask if you can do us(all) one last favour.can you please measure the potential difference between palladium and the legendry MERCURY,king of overpotentials(O.8v +)under hydrogen gas in 1M caustic soda and report your result here for us.

[pomodoro]

I've already done that when I dipped the copper electrode in mercury and painted it till it was shiny with hg. It was not high.  I have to look at the book at work and  will also do it again on a video next week instead of doing graphite again. Then I'm packing up. Thing is profitis the hydrogen overpotential in books is what is required in electrolysis mode to generate hydrogen on that metal compared to a Pt in same solution.  It doesn't predict the electrode rest potential one bit.
I'm disappointed the experiment failed for me but it shouldn't stop other keen discoverers doing their own tinkering.

Pomodoro thanks again for all the time and money you have put into testing out Profitis' ideas.  I think that you have gone above and beyond with your efforts.  Despite the negative results, well conducted experiments like yours are useful demonstrations of the care that it takes to conduct a good experiment.

If Profitis wishes to challenge your results, then I think he is going to have to come up with those text book references that he has long claimed back his contentions, and/or conduct defensible experiments such as you have, but which generate results consistent with rather than contradictory to his claims.
