It is hard to notice in the equasion but the "Ag0" is actually Ag"zero" and not Ag"oh". I guess that the author wanted differentiate the charge of the silver since he had started with Ag+. As I read it, "2 Ag0" is the same as "2Ag". So it does show the conversion of silver ions to metallic silver. - Steve N

The reaction is: > >2 Ag+ + H2O2 ----> 2 Ag0 + H2O + 1/2 O2 2 AgO looks like silver oxide to me, not metallic silver unless I missed a definition somewhere...like rust is metallic iron. That would explain why EIS [CS] turns murky brown if the H2O2 is added before the ions hydrate and "hide out"..the murkiness would be an Oxygen emulsion and the brown color, the oxide. Gong into another definition in context with waste treatment: "Ionic silver" will be something like Silver Acetate solution and not "just" silver ions in water.
