    In nitroprusside ion, the iron and NO exist as\[F{{e}^{2+}}\] and \[N{{O}^{+}}\] rather than \[F{{e}^{3+}}\]and\[NO\]. These forms can be differentiated by

    A)  estimating the concentration of iron

    B)  measuring the concentration of \[C{{N}^{-}}\]

    C)  measuring the solid state magnetic moment

    D)  thermally decomposing the compound

    Correct Answer: C

    Solution :

                     The existance of \[F{{e}^{2+}}\]and \[N{{O}^{+}}\]in nitroprusside ion, \[{{[Fe{{(CN)}_{5}}NO]}^{2-}}\]can be established by measuring the magnetic moment of the solid compound which should correspond to\[(F{{e}^{2+}}=3{{d}^{6}})\]four unpaired electrons.
