Answer

Question

What happens when H₂S is passed into AgNO₃ solution?

Answer

When H₂S is passed into AgNO₃ solution, a white precipitate of Ag₂S (silver sulfide) is formed according to the following chemical equation:

2AgNO₃ (aq) + H₂S (g) → Ag₂S↓ (s) + 2HNO₃ (aq)

The white precipitate of Ag₂S is insoluble in water and can be used as a confirmatory test for the presence of H₂S in a given sample.
