Suppose you have a solution that might contain any or all of thefollowing cations: Cu2+, Ag+,Ba2+, annd Mn2+. Addition of HCl causes aprecipitate to form. After the precipitate is filtered off,H2SO4 is added to the supernate and anotherprecipitate forms. This precipitate is filtered off and a solutionof NaOH is added to the supernatant liquid until it is stronglyalkaline. No precipitate is formed. Which ions are present in eachof the precipitates? Which cations are not present in the originalsolution? Explain your answer.
