QQuestion
Write with balanced chemical equation, what happens when hydrogen sulphide is passed through aqueous solution of lead nitrate.
✓Answer
When hydrogen sulphide (H₂S) is passed through an aqueous solution of lead nitrate [Pb(NO₃)₂], a black precipitate of lead sulphide (PbS) is formed and nitric acid (HNO₃) is produced.
Balanced Chemical Equation:
Pb(NO₃)₂ + H₂S → PbS↓ + 2HNO₃
Observation:
A black precipitate of lead sulphide (PbS) is formed.
