A solution may contain Ag*, Pb²+, Hg₂². A white precipitate forms on addition of 6 M HCI. The precipitate is partially soluble in hot water. The residue turns black on addition of ammonia, NH3 (aq). Which of the ions are present, which are absent, and which remain undetermined? State your reasoning for all three ions! (Assume the student doing this analysis has perfect technique. Remember you may not have to do all of the steps to be sure an ion is present.)
