You first treated your unknown solution with and and a yellow precipitate formed. The liquid remaining atop this precipitate was removed after centrifugation, and to it was added . No new precipitate formed. Next, a solution of was added to the unknown solution which had been treated in the fashion described. A white precipitate formed. This mixture was centrifuged and separated, and the clear solution was then treated with . No precipitate formed. Which metal ions were present in your unknown? Which metal ions were absent?

A solution containing possibly Ag+ , Hg2 2+ and/or Pb2+ ions was treated with 6 M HCl and a white precipitate resulted. The precipitate was treated with hot water and filtered. The filtrate from the hot water filtration was cooled and treated with HCl solution. At that time, a white precipitate resulted. A white residue on the filter paper was treated with NH3, and it disappeared. (2p) Group II Refer to the Flow Chart for Group II to answer following questions. Treatment of an unknown solution with H2S and pH 0.5 produced a black-brown precipitate. The precipitate was treated with KOH.
