Question
We have a blue colored solution of CuSO4 in a concentration of 0.1 M. What is the necessary concentration of chlorides that must be added to 1 L of solution so that it becomes yellow?
 
[Cu(H2O)4]2+ + 4Cl-  ⇄ [CuCl4]2-  + 4 H2O     Kf = 4.2 × 105
      Blue                               yellow
 
For the yellow color to be visible, we consider that 99% of [Cu(H2O)4]2+ is in the form of [CuCl4]2-
