Without performing detailed calculations, show why you would expect the concentrations of the various ammineaqua complex ions

Question:

Without performing detailed calculations, show why you would expect the concentrations of the various ammine–aqua complex ions to be negligible compared with that of [Cu(NH₃)₄]²⁺ in a solution having a total Cu(II) concentration of 0.10 M and a total concentration of NH₃ of 1.0 M. Under what conditions would the concentrations of these ammine–aqua complex ions (such as [Cu(H₂O)₃NH₃]²⁺) become more significant relative to the concentration of [Cu(NH₃)₄]²⁺? Explain.
