Suppose you have a solution that might contain any or all of the following cations: Cu2+, Ag+, Ba2+, and Mn2+. The addition of HBr causes a precipitate to form. After the precipitate is filtered off, H2SO4 is added to the supernate, and another precipitate forms. This precipitate is filtedred off, and a solution of NaOH is added to the supnatant 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?
