Suppose you have a solution that might contain any or all of the following cations: Cu2+, Ag , Ba , and Mn2 . The addition of HBr causes a precipitate to form. After the precipitate is separated by filtration, H2S04 is added to the supernatant liquid, and another precipitate forms. This precipitate is separated by filtration, and a solution of NaOH is added to the supernatant liquid until it is strongly alkaline. No precipitate is formed. Which ions are present in each of the precipitates? Which cations are not present in the original solution?

The given reactions are Cu2+, Ag, Ba, and Mn2+.
