The chemical formula of sodium nitroprusside is:Na2[Fe(CN)5NO]
if NO is neutral i.e 0,and CN is -1.then this formula can be return as [Fe(CN)5NO]2-
we get by substituting let Fe be x,
X+(-1)5+0=-2
X-5=-2
X=-2+5=+3
=> sodium pentacyanonitrosyl ferrate(III)
If we NO is cation i.e NO- so the value will be -1
Then
X=+2
