15. Victoria added 6 M HCI to a sample of the unknown, containing at least one of the Group I cations. A large amount of light-colored precipitate formed. The precipitate was separated from the supernatant liquid and was found to be insoluble in hot water. The colorless supernatant liquid was separated from the precipitate and after cooling and adding K2CRO4, no precipitate resulted. The separated precipitate dissolved completely after adding 6M NH3. A white precipitate was formed, upon addition of 6M HNO3. What cation(s) may be present in the sample? a. Pb2+ b. Ag* c. Hg,2+ d. Ag*, Hg22* e. Pb2", Ag*
