No, you are missing what he is trying to show. He is leaving out the anion (or cation, I always confuse the two). That is he is not showing the oxygen, nitrate, carbonate or whatever that is there as well. That threw me as well. If you take one of them, Silver nitrate for example, then the full equations are as follows: 2AgNO3 + H2O2 --> 2Ag + O2 + 2HNO3 (silver oxygen and nitric acid) then Ag + H2O2 --> AgO + 2H2O or 2Ag + 2H2O2 --> Ag2O + 2H2O + O2 Thus the only thing evolved is oxygen, which is correct. > > On the other hand, you could also have the following equation: > > 2Ag(+) + H2O2 --> 2Ag(+) + H2O2 > > In other words, H2O2 has no effect on silver ions. You are ignoring the cationn(or anion) which is part of the equation. He is simply leaving it out by indicating ionized state of H+, because he is assuming any of them in there and they all act the same. > > > BTW, Marshall, have you posted any charge-balanced equations to > support your hypothesis that H2O2 turns Ag+ to AgO or Ag2O? If so, > can you explain the experiment I just proposed that Ken runs? I have posted the equations. Check the precious message. I think the experiment would be a good one with what I indicated, but as you wrote it it would prove nothing, since AgCl would be formed no matter what, it is not a matter of if it is formed, but how much.
