Sodium nitroprusside gives a violet colour with sulphide ions. The compound (formed in this test) is:
Show Hint
Sulphide converts nitrosyl (NO) to NOS in nitroprusside's 5-cyanide complex.

- Na2[Fe(NO)(CNS)5]
- H3[Fe(CN)6]
- Na4[Fe(NOS)(CN)6]
- Na4[Fe(NOS)(CN)5]
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Sodium nitroprusside is Na2[Fe(CN)5NO].
Step 2: S2- attacks the nitrosyl group directly, forming NOS ligand while 5 CN remain.
Step 3: This raises complex charge from 2- to 4-, needing 4 Na+.
