Marshall D, Thanks for your reply, and thanks for the informative link <g>
Try this, for an insight to the process of electrolysis, just substitute Ag (0.79V) for chlorine at the anode. http://scifun.chem.wisc.edu/chemweek/cl2&naoh/Cl2&NaOH.html Silver hydroxide can only degrade if it is a compound and not dissolved ions Ag+ and OH- . If water is being reduced to H2 gas at the cathode (0.83V) then most likely silver is not (0.79V). H2 gas is formed at the start of the process when no silver ion are available for reduction, and intermittently throughout the generating process when Ag+ concentration is low in the cathode vicinity, or so I theorise.
