(a) S2-+ Ag + arrow Ag 2 S soluble in hot HNO 3 (b) S 2-+ BaCl 2 arrow no reaction (c) Na 2 S + Na 2[ Fe ( CN )5 NO ] arrow underset textpurple colourNa 4[ Fe ( CN )5 NOS ]

Q. Which of the following statement $(s)$ is/are correct?

Sulphide gives black precipitate with $A g N O_{3}$ solution and is soluble in hot concentrated nitric acid

Sulphide gives no precipitate with barium chloride solution

Sulphide ions react with sodium nitroprusside giving a purple colouration

All of these

(a) $S^{2 -} + A g^{+} \to A g_{2} S$ soluble in hot $H N O_{3}$

(b) $S^{2 -} + B a C l_{2} \to$ no reaction

(c) $N a_{2} S + N a_{2} [F e (CN)_{5} NO] \to purple colour N a_{4} [F e (CN)_{5} NOS]$
