A solution containing a mixture of metal cations was treated with dilute HCl and a precipitate formed. The solution was filtered and H,S was bubbled through the acidic solution. A precipitate again formed and was filtered off. Then, the pH was raised to about 8 and H2S was again bubbled through the solution. This time, no precipitate formed. Finally, the solution was treated with a sodium carbonate solution, which resulted in the formation of a precipitate. Classify the metal ions based on whether they were definitely absent from the original mixture or whether it is possible they were present in the original mixture? Definitely absent Possibly present Ag* Cu2+ Ba2+ Mn2+ Ni2+ A3+ Lit Sn4+ Mg²+ Hg2+ Sb+ Hg2+ Pb2+
