Question

write the name of the complex formed when sodium nitroprusside is added to os of mixture in the confirmatory test of sulphide ion​

Answer 1

Explanation:

Sodium nitroprusside when added to an alkaline solution of sulphide ion produces purple colouration due to the formation of sodium thionitroprusside complex which is purple in colour.

Answer 2

Answer:

the name of the complex formed when sodium nitroprusside is added to os of mixture in the confirmatory test of sulphide ion​ is $Na_{4}[Fe(CN)_{5} NOS]$

Explanation:

• Different elements react in chemistry to create compounds. There are many states that the compounds go through throughout a reaction. There is the generation of released gases and intermediate ions products. These components and goods don't necessarily need to be clearly visible and easy to distinguish. So certain responses are taken into account as the element's test in order to discover such elements.

• The presence of sulphide anion is established by treating a salt alkaline water extract with a few drops of sodium nitroprusside solution.

• The existence of sulphide ore is confirmed by the presence of purple or violet coloration.
  
  $S^{2-}+Na_{2}Fe(CN)_{5}NO] \rightarrow Na_{4} [Fe(CN)_{5}NOS]\\ Sodium\; nitroprusside\: \;\;\;\;\;\;\;\; Complex \;of \;violet \;colour$
