Question- In qualitative analysis, Ag+, Hg2+2 and Pb2+ are separated from other cations by the addition of HCl.
Part A. Calculate the concentration of Cl? required to just begin the precipitation of AgCl in a solution having metal-ion concentrations of 0.036M.
Part B. Calculate the concentration of Cl? required to just begin the precipitation of Hg2Cl2 in a solution having metal-ion concentrations of 0.036M.
Part C. Calculate the concentration of Cl? required to just begin the precipitation of PbCl2 in a solution having metal-ion concentrations of 0.036M.
Part D. What fraction of the Pb2+ remains in the solution when the Ag+ just begins to precipitate?
If possible just a brief explanation how you got the answer?
