Why the complex potassium Trioxalato Ferrate III is colored?
Potassium acts as a counterion, balancing the 3- charge of the complex. Crystals of the trihydrated form of the complex, K3[Fe(C2O4)3]. 3H2O, are emerald green in colour. In solution the complex dissociates to give the ferrioxalate anion, [Fe(C2O4)3]3-, which appears fluorescent green in colour.
