What do we get when sodium nitroprusside solution reacts with sodium sulphide?

Academic Chemistry NCERT Class 6

The reaction of sodium nitroprusside with sodium sulphide gives a purple colour solution of sodium thio nitroprusside.

Sodium nitroprusside → Na2[Fe(CN)5NO]

Sodium sulphide + Sodium nitroprusside --> sodium thio nitroprusside

Na2S+ Na2[Fe(CN)5NO] → sodium thio nitroprusside (purple colour).
