A 50.0 mL sample containing Cd2 and Mn2 was treated with 62.6 mL of 0.0600 M EDTA. Titration of the excess unreacted EDTA required 19.1 mL of 0.0330 M Ca2 . The Cd2 was displaced from EDTA by the addition of an excess of CN-. Titration of the newly freed EDTA required 23.5 mL of 0.0330 M Ca2 . What were the molarities of Cd2 and Mn2 in the original solution?
