Question Description

I’m trying to learn for my Chemistry class and I’m stuck. Can you help?

The formation constant for the metal–EDTA complex (where EDTA is indicated by the symbol Y) can be expressed for the net equilibrium reaction as:

Mn+ + Y4– ⇌ (MY)n–4 with Kf = [(MY)n-4]/[Mn+][Y4–]

Based upon this information only, which one of the following metal cations present in the same mixture would you expect to react with EDTA first?

Calcium (Ca2+), Kf=10.7

Cerium (Ce3+), Kf = 15.9

Lead (Pb2+), Kf = 18.0

Zinc (Zn2+), Kf = 16.7
