Problem- You have a solution that contains 0.1 M Ag+, 0.1 M Cu2+ and 0.1 M Ba2+. You would like to separate these ions by precipitation. For quality purposes, the relative error must be below 0.1%, i.e., the precipitation of each ion must be complete (>99.9%) and there must not be more than 0.1% (by weight) of one of the other ions in the precipitate. Explain your answer: nature of precipitate, pH, concentrations etc. Be quantitative in your answer.

Write the complete solution in short and simple way
