Question

One method to determine the amount of uncomplexed Sn2+ in a solution would be to use a chelating

agent such as ethylenediamminetetraacidic acid (EDTA) via the following reaction:

Sn2+ (aq) + EDTA4-(aq) %u2190%u2192 [SnEDTA2-] (aq) Kf= 2.0 x1018

EDTA is a polyprotic acid. Therefore, the concentration of EDTA4-shown in the above reaction would depend on the fraction of EDTA4- existing at a certain pH of the solution. If this titration reaction was done at a pH = 10.00, what would be the a EDTA4-? (Use information from Table 9.8.)

Then what would be the value of K%u2019f?

aEDTA4-= _______; K%u2019f= __________

Explanation / Answer
