A 50.0 mL sample containing Cd^2+ and Mn^2+ was treated with 42.8 mL of 0.0500 M EDTA. Titration of the excess unreacted EDTA required 17.8 mL of 0.0250 M Ca^2+. The Cd^2+ was displaced from EDTA by the addition of an excess of CN Titration of the newly freed EDTA required 27.1 mL of 0.0250 M Ca^2+. What are the concentrations of Cd^2+ and Mn^2+ in the original solution?
