Hydroxide releases hydrogen and carbonate release CO2. So all you wind up with is silver oxide.

Frank: I don't understand. Aren't you saying that the solubility limit of silver is governed by the solubility product of silver carbonate or silver hydroxide? So why wouldn't an UNADULTERATED residue contain one or both of these compounds? When exactly do these decomposition reactions take place? Is it while water is evaporated from the sample, or are you talking about something else? Surely there must be a way to prep such a residue without driving off CO2 or hydrogen. Failing that approach, various types of microscopic phase identification and analyses could be tried. Roger -- The silver-list is a moderated forum for discussion of colloidal silver.
