I have run the same experiment twice, and both times got a tan colored covering on the wire, and when the H2O2 completely evaporated, got a tan colored precipitate on the bottom of the glass. Since silver oxide has a solubility of 13 ppm, you may be using too much H2O2. I put a 2 inch piece of 14 guage silver wire in the bottom of a short 4 oz glass, and added just enough H2O2 to cover the bottom and the wire completely, I then let it set and watched it. After a day or two once the solubility limit of silver oxide was reached, the film on the wire formed, and after another day or so the liquid evaporated leaving behind the tan precipitate on the bottom as well. When I added some H2O2 to this (an inch or so deep), both the tan on the bottom and the tan on the wire dissolved back leaving a clear liquid again. > > > >3.

I have never gotten the white precipitate. I can't think of any way hydrogen peroxide would convert silver oxide to silver hydroxide, and the ionic portion should have been silver hydroxide to start with, and it was in solution. I would think that it might be forming silver peroxide, but silver peroxide is gray or black, not white. Maybe the initial is silver peroxide and the white is silver oxide. > > Whatever is going on with that, the weirdnesses don't stop there.

I am not surprised by that since H2O2 can make silver oxide from silver particles, and silver particles from silver hydroxide, concentrations, temperature, and so forth could easily change the dymanics, plus it may be making something else as you seem to think as well. > > > >4.

[Look!, a quack! > DUCK! ] Have at it, and good luck. I wish we could identify the white precipitate conclusively. I wonder if we are getting a reaction from the stabalizer in H2O2, something I had not considered before. >From what I can find H2O2 is normally stabalized with acetanilide, or acetic acid amid ( CH3CONH2 ) Now, if we get a reaction between silver and this it could produce silver acetate, which IS white. But you would have to add a good bit of H2O2 I would imagine since there is very little stabalizer in H2O2. Also silver acetate is soluble, so it should not form a precipitate, so that really does not make any sense either.
