To preserve freshness in a salad dressing by complexing a metal ion which could catalyze oxidation, 1.00 x 10-3 M EDTA is added. Assuming that the metal is present at a concentration of 2.6 x 10-6 M, and that under these conditions β1 for the metal-EDTA complex is 7.15 x 1011, what fraction of the metal is left uncomplexed in the salad dressing? (Hint: can you think of an assumption that will let you avoid having to use an ICE table?)
