How could you use a precipitation reaction to separate the two metal ions? We could add HF (aq) to obtain a precipitate of AgF (s). We could add more H2O to obtain a precipitate of AgOH(s). We could add HCl (aq) to obtain a precipitate of AgCl (s). o We could add HCl (aq) to obtain a precipitate of NaCl(s).

2. Can Na2SO4 be used as a precipitating agent to separate a mixture of Fe2+ and Ca2+? Explain. 3. Can ammonia be used as a precipitating agent to separate a mixture of Al3+ and Cu2+? Explain. Describe a possible step-by-step procedure for separating a mixture of Ca2+, Al3+, Fe3+, and Zn2+. Be clear about what precipitating agent you will add in what order, and what will get filtered out at each step. At the end, you should have each of...

A solution containing a mixture of metal cations was treated with dilute HCl and no precipitate...
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. Which metal ions were definately present, which were definitely...

A solution containing a mixture of metal cations was treated as outlined. 1. Dilute HCl was added and a precipitate formed. The precipitate was filtered off. 2. H,S was bubbled through the acidic solution. Again, a precipitate formed and was filtered off. 3. The pH was raised to about 9 and H,S was again bubbled through the solution. No precipitate formed. 4. Finally, sodium carbonate was added. A precipitate formed and was filtered off. What can be said about the...
