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
