In nitroprusside ion, the iron and NO exist as ${\rm{F}}{{\rm{e}}^{{\rm{II}}}}$ and $N{O^ + }$ rather than $F{e^{III}}$ and NO. These forms can be differentiated by:

Estimating the concentration of iron

Measuring the concentration of ${\rm{C}}{{\rm{N}}^ - }$

Thermally decomposing the compound

In nitroprusside ion, the iron and NO exist as

\mathrm{F}{\mathrm{e}^{\mathrm{II}}}

and

N{O^ + }

rather than

F{e^{III}}

and NO. These forms can be differentiated by:

View answer and explanation

Correct option: C

Measuring the solid state magnetic moment

Option C is correct because the magnetic moment depends on the number of unpaired electrons, which differs between

\mathrm{F}{\mathrm{e}^{\mathrm{II}}}

and

F{e^{III}}
