Vedclass · Answer

(B) In solution,coordination compounds like $[Fe(CN)_6]^{3-}$ and $[Fe(CN)_6]^{4-}$ do not dissociate to give free $Fe^{3+}$ or $Fe^{2+}$ ions because the iron is part of the stable complex ion.$(NH_4)_2SO_4 \cdot FeSO_4 \cdot 6H_2O$ (Mohr's salt) dissociates to give $Fe^{2+}$ ions.$Fe_2(SO_4)_3$ is an ionic salt that dissociates completely in water as follows:$Fe_2(SO_4)_3 \rightarrow 2Fe^{3+} + 3SO_4^{2-}$Thus,$Fe_2(SO_4)_3$ provides $Fe^{3+}$ ions in solution.
