You are given an aqueous solution and are asked to analyze it for the presence (or absence) of ag+(aq), ca2+(aq), and/or hg2+(aq) ions. there are no other metal ions in the solution.  you add aqueous hydrochloric acid (hcl) to the solution, and nothing appears to happen.  you add aqueous sulfuric acid (h2so4) to the solution, and a white precipitate forms.  you remove (via filtration) the white precipitate, and then add aqueous hydrogen sulfide (h2s) to the solution that remains. a black precipitate forms. based on these observations, which ions are present in the original solution? (a) ag+(aq), ca2+(aq), and hg2+(aq) (b) only ag+(aq) and hg2+(aq) (c) only ca2+(aq) and hg2+(aq) (d) only ag+(aq) and ca2+(aq) (e) only hg2+(aq)
