Question: Estimate the total [Cl ] required in a solution that is initially 0.10 M CuSO 4 to produce a visible yellow color. Assume that

Estimate the total [Cl^–] required in a solution that is initially 0.10 M CuSO₄ to produce a visible yellow color.

[Cu(HO)4]+ + 4Cl = (blue) [CuCl4] (yellow) + 4HO Kf = 4.2 x 105

Assume that 99% conversion of [Cu(H₂O)₄]²⁺ to [CuCl₄]^2–is sufficient for this to happen, and ignore the presence of any mixed aqua–chlorido complex ions.

[Cu(HO)4]+ + 4Cl = (blue) [CuCl4] (yellow) + 4H0 Kf = 4.2 x 105
