A 50.0 mL sample containing Cd²+ and Mn²+ was treated with 60.9 mL of 0.0700 M EDTA. Titration of the excess unreacted EDTA required 18.9 mL of 0.0220 M Ca2+. The Cd²+ was displaced from EDTA by the addition of an excess of CN. Titration of the newly freed EDTA required 16.3 mL of 0.0220 M Ca²+. What are the concentrations of Cd²+ and Mn2+ in the original solution? concentration: M Mn2+ concentration: M Cd2+
