I may be wrong, but I can spot an error. For the 'Deep blue solution' is it not [Cu(NH3)4(H2O)2] 2+ ? In your version, it has 2 OH- molecules instead of 2 H20 molecules within the complex, surely this would make the species neutrally charged and actually be a precipitate? Helpful quiz none the less!
