Question
The formation constant for FeY - is 1.3 x 10 25 . Calculate the concentration of free Fe 3+ in a FeY - 0.10 M
The formation constant for FeY- is 1.3 x 1025. Calculate the concentration of free Fe3+ in a FeY- 0.10 M solution at pH 4.00 and pH 1.00 and explain at what pH it is more convenient to carry out a titration with EDTA for Fe3+, sketch the form that the titration curves for this complex would have at the two pH's: answer: a) pH 4.00 [Fe3+] = 1.4 x 10-9 M and at pH 1.00, Fe3+] = 6.4 x 10-5 M.
