Sulphide ions react with Na(2)[Fe(NO)(CN...

Sulphide ions react with `Na_(2)[Fe(NO)(CN)_(5)]` from a purple coloured compound `Na_(4)[Fe(CN)_(5)(NOS)]`. In the reaction, the oxidation state of iron

A

changes from +2 to +3

B

changes from +3 to +2

C

changes from +2 to +4

D

does not change

Text Solution

Verified by Experts

The correct Answer is:
D
No change in oxidation state
`Na_(2)[Fe^(2+)(NO)(CN)_(5)]+Na_(2)S to Na_(4)[Fe^(+2)(NOS)(CN)_(5)]`
