Vedclass · Answer

(C) The characteristic test for an ion is given only if the ion is present in the ionization sphere (i.e.,it dissociates in water).In the complex $K_3[Fe(CN)_6]$,the iron is present as a part of the coordination entity $[Fe(CN)_6]^{3-}$.Since the coordination sphere does not dissociate to give free $Fe^{3+}$ ions in an aqueous solution,it will not give the characteristic test for $Fe^{3+}$ ions.Other compounds like $K_2Fe_2(SO_4)_4 \cdot 24H_2O$ (Potash Alum variant),$(NH_4)_2Fe(SO_4)_2 \cdot 6H_2O$ (Mohr's salt),and $Fe_2(SO_4)_3$ are simple salts that dissociate completely in water to provide free iron ions.

Which of the following will $NOT$ give the characteristic test for $Fe^{2+}$ or $Fe^{3+}$ ions?
