Sulphide ions react with Na₄[Fe(NO)(CN)₅] to form a purple-coloured compound Na₄[Fe(CN)₅(NOS)]. In the reaction, the oxidation state of iron
Options:
Answer:
D
Solution:
In the nitroprusside ion [Fe(NO)(CN)₅]⁴⁻, NO is present as NO⁺: x + 1 - 5 = -4 ⇒ x = +2. Sulphide merely adds to the coordinated nitrosyl to give [Fe(CN)₅(NOS)]⁴⁻; iron stays +2. Hence (d).
