Suppose you have a solution that might contain any or all of the following cations: Ag , Ba , and Fe . + 2+ 3+ 2 4 When excess HCl is added to this solution a precipitate forms. This precipitate is removed and excess H SO is then added to the solution which forms a precipitate. This precipitate is removed and excess NaOH is added to the supernatant until the solution is strongly basic. The addition of the NaOH does not produce a precipitate. What is the chemical formula of each precipitate? Which of the 3 possible metal cation(s) were not present in the original solution? (explain)
