Consider the titration of a 50.00 mL aliquot of a water sample containing Fe³⁺+ and Pb²⁺+ with 19.62 mL of 0.00243 M EDTA to reach the end point. Excess CN^- was added to a separate 20.00 mL aliquot of the same water sample, causing Fe(CN)₃ to precipitate. This aliquot was titrated with 2.01 mL of 0.00243 M EDTA to reach the end point. What is the molarity of Fe³⁺ in the water sample?

Please explain every step. Thank you.

21.83 mL of a Pb2 solution, containing excess Pb2 , was added to 10.75 mL of a 2,3-dimercapto-1-propanol (BAL) solution of unknown concentration, forming the 1:1 Pb2 –BAL complex. The excess Pb2 was titrated with 0.0141 M EDTA, requiring 8.86 mL to reach the equivalence point. Separately, 40.70 mL of the EDTA solution was required to titrate 31.00 mL of the Pb2 solution. Calculate the BAL concentration, in molarity, of the original 10.75-mL solution.
