Question

Violet coloured complex obtained in the detection of sulphur is (A)  Na2[Fe(NO)(CN)5]  (B)  Na3[Fe(ONS)(CN)5]  (C)  Na4[Fe(CN)5NOS]  (D) Both (b) and (c)

Tardigrade Admin · Accepted Answer

Sulphur of organic compounds is detected by using sodium nitroprusside. With it sulphur forms a violet colour complex, called sodium thionitroprusside.

N a_{2} S + sodium nitroprusside N a_{2} [F e (CN)_{5} NO] \to sodium thionitroprusside N a_{4} [F e (CN)_{5} NOS]

Q. Violet coloured complex obtained in the detection of sulphur is

$N a_{2} [F e (NO) (CN)_{5}]$

$N a_{3} [F e (ONS) (CN)_{5}]$

$N a_{4} [F e (CN)_{5} NOS]$
