Question

Write a confirmatory test for sulphide ion​

Answer 1

Answer:

Silver nitrate and aqueous sulfide solution

Add silver nitrate to aqueous sulfide solution. It gives black silver sulfide precipitate which is not soluble in dilute nitric acid. But it will dissolve in concentrated nitric acid.

With dilute acids

Add dilute acid to a solid sulfide. Hydrogen sulfide acid (H2S) is produced which is an weak dibasic acid.

Hope this will help.
