A 1.00 L solution contains 2.00 X 10^-4 M Cu(No3)2 and 1.2 x 10^-3 M Ethylenediamine (en). The Kf for Cu(en)2 2+ is 1.0X10^20 What is the concentration of Cu 2+ (aq) in the solution?
The concentration of Cu2+(aq) in the solution is:
You can resolve your exercise, considering the stoichiometric ratios
analyzing the exercise in this way, there is not Cu2+(aq) in solution, because all Cu is forming the complex with the ethylenediamine.
I hope this answer your help.
If that is not so, my apologies, the exercise is not clear to
solve.
