Have you attempted to do that? Roger No, I have not. Both silver carbonate and silver hydroxide reduce to silver oxide. Hydroxide releases hydrogen and carbonate release CO2. So all you wind up with is silver oxide. For more details, see my write up on what happens as water is evaporated from a high ionic solution in the FAQ. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
