Hi KD'C, What strength H2O2 are you using, I would guess 3% as you put some in your mouth without burning it!
I have posted experiments (along with others) in the past, using 50% H2O2. If you care to check the archives, you may find the answers to most of your questions there. H2O2 does react with pure metallic silver, in fact passing high concentration H2O2 through a silver mesh is a method used in DIY rocket engines! A small length (10mm) of new silver wire was left in 100mls of 50% H2O2 for a few days. A small stream of bubbles emanated from the silver and the concentration of silver ions in the solution increased from zero to well above 20ppm, as measured by Ion Selective Electrode (ISE). There was no silver oxide. A nasty brew of dirty grey (inclusion of large uncharged metallic colloids, emanating from the cathode) CS was created, there was much fallout on the bottom of the container. Some of this colloid was taken, to which a few ml of 50% H2O2 was added. A great cloud of minute bubbles formed immediately, which were so small that the solution looked milky, and the Tyndal beam showed a shower of sparklies. Within a few hours the solution was completely clear, showing very little Tyndal effect. The concentration of silver ions increased as the solution cleared. I concluded that the H2O2 oxidised the metallic silver particles as it reduced to O2 gas and water, forming free silver ions and not silver oxide. You talk of the 'oxide load', what do you mean? Is this the build up on the neg. cathode or pos. anode, fall out on the bottom of the container or floaters on the solution surface, or colour in the solution?
