A solution containing a mixture of metal cations was treated as outlined. Dilute HClHCl was added and no precipitate formed. H2SH2S was bubbled through the acidic solution. A precipitate formed and was filtered off. The pH was raised to about 99 and H2SH2S was again bubbled through the solution. A precipitate formed and was filtered off. Finally, sodium carbonate was added to the filtered solution and no precipitate formed. What can be said about the presence of each of these...
