A 50.0 mL sample containing Cd²+ and Mn²+ was treated with 58.6 mL of 0.0700 M EDTA. Titration of the excess unreacted EDTA required 12.5 mL of 0.0180 M Ca²+. The Cd²+ was displaced from EDTA by the addition of an excess of CN-. Titration of the newly freed EDTA required 24.9 mL of 0.0180 M Ca²+. What are the concentrations of Cd²+ and Mn²+ in the original solution? concentration: concentration: M Mn²+ MCd2+
