Question

Nitroprusside ion is
A: $\left[F{e}^{II}\right(CN{)}_{5}N{O}^{+}{]}^{2+}$
B: $\left[F{e}^{III}\right(CO{)}_{5}NO{]}^{2+}$. A and B can be differentiated by:

• A. Estimating the concentration of iron
• B. Measuring the concentration of $C{N}^{-}$
• C. Measuring the magnetic moment
• D. Thermally decomposing the compound

Answer 1

Answer: (C)

Measuring the magnetic moment

Nitroprusside ion is $\left[F{e}^{II}\right(CN{)}_{5}N{O}^{+}{]}^{2+}$. $\left[F{e}^{II}\right(CN{)}_{5}N{O}^{+}{]}^{2+}$ and $\left[F{e}^{III}\right(CO{)}_{5}NO{]}^{2+}$ can be differentiated by measuring the magnetic moment because Iron is in different oxidation state in both the compounds.
