It is a brown-black cubic crystal of density 7.14 g/cc. and it decomposes at 300 deg. C. the molar solubility is 5.6 x exp(-5) moles/L, which would make the solubility product constant, at 20 deg.

Frank: Since the solubility products of either silver carbonate or silver hydroxide indicate very low silver solubility, it would appear to be a simple procedure to collect any residue from a LVDC CS process that produced a CS concentration above, say, 20 PPM CS (which is above your proposed silver solubility limit), heat gently to remove any hydrated water, and then use x-ray diffraction to confirm the presence of either silver carbonate or silver hydroxide. Have you attempted to do that? Roger -- The silver-list is a moderated forum for discussion of colloidal silver.
