Ode, I wonder if you can 'shed some light (pun)' on an issue that we ceramists are facing, as to solubility of silver oxide in ceramic water filter media. We saturate the ceramics with concentrated CS, and when these filters dry out there's a reaction that's something like: Ag+ + e + O --> AgO. It's the silver oxide in the filter that disinfects the water. (A phenomenon that only now, after about 3000 years is gaining widespread credibility with scientists.) The question is at the heart of a huge debate among those few ceramists who deal with permeable filtration media, as to just what goes on if the water that's put through the filter contains chlorine. Does the chlorine react with the silver oxide? I'm no chemist by a long shot but I had always thought that silver oxide would be too insoluble for this too happen. Reid
Ode Coyote said That's not light sensitivity. When CS ions lose the water that solvates them, the ions oxidize into silver oxide on exposure to the air. The normal color of silver oxide is black but as i pointed out in a previous post, there at least 3 varieties of silver oxide. One may be reddish or deep yellow or dark orange. I haven't seen a color notation on the differences. Silver oxide is inert. Dried metallic silver is immobile. Both essentially ineffective for different reasons.
