6. A mixture contains at least one of the ions in the silver group (Ag*, Hg²*, Pb²+). Read the following procedure and determine which ions are present. Cold 6M HCl was added to the mixture producing a white precipitate. Hot water was then added and the solution was stirred, and the supernatant decanted to isolate a white precipitate after centrifugation. Sulfuric acid was added to one portion of the supernatant and potassium chromate was added to a second portion of the supernatant, but no precipitates formed. The isolated white precipitate was mixed well with 4 drops of concentrated ammonia. The resulting solution was centrifuged. The supernatant was decanted to show the presence of a grayish-black precipitate. To the supernatant, concentrated nitric acid was added dropwise until blue litmus paper added turned red and a white precipitate was present.
