Question
Transcribed Image Text:A solution containing a mixture of metal cations was treated with dilute HCl and no precipitate formed. Next, H2S was bubbled
through the acidic solution. A precipitate formed and was filtered off. Then, the pH was raised to about 8 and H2S was again
bubbled through the solution. A precipitate again formed and was filtered off. Finally, the solution was treated with a sodium
carbonate solution, which resulted in no precipitation.
Classify the metal ions based on whether they were definitely absent from the original mixture or whether it is possible they
