Question
A 50.0 mL sample containing Cd2+ and Mn2+ was treated with 65.1 mL of 0.0400 M EDTA. Titration of the excess unreacted EDTA required 15.0
A 50.0 mL sample containing Cd2+ and Mn2+ was treated with 65.1 mL of 0.0400 M EDTA. Titration of the excess unreacted EDTA required 15.0 mL of 0.0190 M Ca2+. The Cd2+ was displaced from EDTA by the addition of an excess of CN−. Titration of the newly freed EDTA required 22.7 mL of 0.0190 M Ca2+. What are the concentrations of Cd2+ and Mn2+in the original solution?
