In nitroprusside ion, the iron and `NO` exist as `Fe(II)` and `NO^(+)` rather than `Fe^(III)` and `NO`. These forms can be differentiated byA. Estimating the conectration of ironB. Measuring the concentration of `CN-`C. Measuing the solid state magnetic momentD. Thermally decomposing the compound

Answer» Correct Answer - C
The existence of `Fe^(2+)` and `NO^(+)` in nitroprusside ion `[Fe(CN)_(5) NO]^(2-)` can be established by measuring the magnetic moment of the solid compound which should correspond to `(Fe^(2+) = 3 d^(6))` four un paied electron.
