State titration of the newly freed edta required

Reference no: EM13179531

A 50.0 mL sample containing Cd2 and Mn2 was treated with 49.6 mL of 0.0600 M EDTA. Titration of the excess unreacted EDTA required 13.7 mL of 0.0210 M Ca2 . The Cd2 was displaced from EDTA by the addition of an excess of CN. Titration of the newly freed EDTA required 18.0 mL of 0.0210 M Ca2 . What were the molarities of Cd2 and Mn2 in the original solution?
