Why do you say that silver oxide makes the yellow tint? Yesterday I had a saturated solution of silver oxide, and it appeared crystal clear. I will test again, but I don't think silver oxide dissolved in water has a yellow tint, it is does, it is certainly very light. The yellow tint is caused by particle size. This was proven over 100 years ago, and all tests since then confirm it. If it was silver oxide, how can you explain that it goes to gold, then orange, then red as the particles increase in size? > > > Ag2O + H2O2 = 2Ag(+) + O2 + H2O > > http://butler.cc.tut.fi/~penningt/thesis/9701635/ppt/29/tsld018.htm > That is impossible. AG+ can only be formed two ways, first by EIS with nothing but pure water, and second by being part of a compound, you have to have an anion and cation to get Ag+. I am not sure why you gave me the above url, that supports me. Ag + H2O2 -> AgO + H2O and Ag2O + H2O2 -> Ag2 + H2O. But it does not deal with AgO at all, so I am still trying to confirm if AgO + H2O2 give Ag + H2O or not. I may have this proven one way or the other experimentally shortly. You have taken that site that gives the correct reaction for Ag2O of : Ag2O + H2O2 = 2 Ag + O2 + H2O which shows it produces silver atoms, or a silver particle of 2 atoms and changed it to: Ag2O + H2O2 = 2Ag(+) + O2 + H2O which shows it generating ions, which would not be possible without another element to combine with it. Why did you do that, are you trying to confuse the issue? > > It's not clear that you have established adding H2O2 to cs produces > silver oxide.

CRC handbook of Chemistry and Physics. I did prove that it is soluble to some extent and then saturates at a fairly low level, just did not measure the silver content to verify it was at 13 ppm. > First, that is probably a figure taken from some chemistry > book.

I have repeatedly indicated I am talking about AgO. AgO2 and AgO3 are both referred to as silver peroxide, one one could call them silver dioxide and silver trioxide to differentiate them. > > Anyway, if the soft black stuff that forms on the electrodes at high > current density is soluble, why does it remain on the electrodes? > I never said the black was soluble, I said the brown stuff was slightly soluble, because it is.
