A solution containing a mixture of metal cations was treated with dilute HCl and a precipitate formed. The solution was filtered and H2S 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 formation of a precipitate. Which metal ions were definiately present, which were definately absent, and which may or may not have been present in the original mixture?
a) Hg^2+
b) Pb^2+
c) Ba^2+
d) Zn^2+
e) Fe^2+
f) Co^2+
g) Sn^2+
h) Li^+
i) Ag^+
j) Mg^2+
k) Hg2^2+
l) Sb^3+
m) Cd^2+
