A 50.0 mL sample containing Cd2+ and Mn2+ was treated with 42.5 mL of 0.0700 M EDTA. Titration of the excess unreacted EDTA required 16.8 mL of 0.0120 M Ca2+. The Cd2+ was displaced from EDTA by the addition of an excess of CN–. Titration of the newly freed EDTA required 26.9 mL of 0.0120 M Ca2+. What were the molarities of Cd2+ and Mn2+ in the original solution?
Answer: ([Cd2+] = 0.00646 M; and [Mn2+] = 0.0490 M)

A 25.00 mL sample containing an unknown amount of Al3+ and Pb2+ required 17.03 mL of 0.04947 M EDTA to reach the end point. A 50.00 mL sample of the unknown was then treated with F- to mask the A13+. To the 50.00 mL sample, 25.00 mL of 0.04947 M EDTA was added. The excess EDTA was then titrated with 0.02164 M Mn2+. A total of 25.3 mL was required to reach the methylthymol blue end point. Determine pA13+ and...
