Conditional Formation constant - EDTAQuestion 1: a) How many millimeters of 0.0700 M EDTA are required to react with 50.0 mL of 0.0140 M Cu2+?
b) With 50.0 mL of 0.0140 M Sc3+?
Question 2: a) Find the conditional formation constant for Sr(EDTA)2- at pH 11.00, where log Kf is 8.72 and αY4- is 0.81. = _________
b) Find the concentration of free Sr2+ in 0.65 M Na2[Sr(EDTA)] at pH 11.00. [Sr2+] = ________M
Hint:
The conditional formation constant is given by
Where is the fraction of EDTA in the form Y4- at the given pH, and Kf is the formation constant for the given metal-EDTA complex.
