olution containing a mixture of metal cations was treated with dilute HCl and no precipitate formed.
A solution containing a mixture of metal cations was treated with dilute and no precipitate formed. Next, was bubbled through the acidic solution. A precipitate formed and was filtered off. Then, the pH was raised to about and 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
present, definitely absent, or whether it is possible they were present
in the original mixture. No referals unless it contains all of the ions listed that I have.

Qualitative analysis of metal cations
Adding HCl: no precipitate formed
Group I cations : Ag+, Pb2+, Hg2^2+ absent
Adding H2S: precipitate formed
Group II cations present: Sn4+, Cd2+, Sb3+, Hg2+
Raising pH to 8, and added H2S: precipitate formed
Group III cations present: Al3+, Ni2+, Mn2+
Added Na2CO3: no-precipitate formed
Group IV cations absent : Ba2+, Mg2+
So,
Definitely present
Sn4+, Cd2+, Sb3+, Hg2+
Mn2+, Ni2+
Definitely absent
Ag+, Hg2^2+, Pb2+, Ba2+, Mg2+
Possibly present
Al3+, K+

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.
