Macmillan Learning O A solution containing a mixture of metal cations was treated as outlined. 1. Dilute HCI was added and a precipitate formed. The precipitate was filtered off. 2. H₂S was bubbled through the acidic solution. Again, a precipitate formed and was filtered off. 3. The pH was raised to about 9 and H₂S was again bubbled through the solution. No precipitate formed. 4. Finally, sodium carbonate was added. A precipitate formed and was filtered off. What can be said about the presence of each of these groups of cations in the original solution? Cation group Ag+, Pb²+, Hg2+ Bi³+, Cd²+, Cu²+, Hg²+, Pb²+, Sb +, Sn²+, Sn+ AP+, Co²+, Cr, Fe²+, Fe³+, Ni²+, Mn²+, Zn²+ Ba²+, Ca²+, Mg²+, SP2²+ Li+, Na+, K+, NH; Description form insoluble chlorides form acid-insoluble sulfides form base-insoluble sulfides or hydroxides form insoluble carbonates completely soluble Present in the original solution? Answer Bank At least one of these ions was present. All of these ions were present. unknown None of these ions were present.
