Asolution containing a mixture of metal cations was treated as outlined. dilute hcl was added and a precipitate formed. the precipitate was filtered off. h 2 s was bubbled through the acidic solution. again, a precipitate formed and was filtered off. the ph was raised to about 9 and h 2 s was again bubbled through the solution. no precipitate formed. finally, sodium carbonate was added. a precipitate formed and was filtered off. what can be said about the presence of each of these groups of cations in the original solution?
