Vedclass · Answer

(C) The reaction between acidified potassium permanganate $(KMnO_4)$ and ferrous ammonium sulphate $(FeSO_4 \cdot (NH_4)_2SO_4 \cdot 6H_2O)$ involves the oxidation of ferrous ions to ferric ions.The balanced ionic equation is: $5Fe^{2+} + MnO_4^- + 8H^+ \rightarrow 5Fe^{3+} + Mn^{2+} + 4H_2O$.Here,$Fe^{2+}$ is oxidised to $Fe^{3+}$ while $MnO_4^-$ is reduced to $Mn^{2+}$.Therefore,the correct option is $C$.
