QQuestion
Write, with the balanced chemical equation, what happens when H2S gas is passed through an aqueous solution of Pb(NO3)2.
✓Answer
When hydrogen sulfide (H2S) gas is passed through an aqueous solution of lead(II) nitrate (Pb(NO3)2), a chemical reaction occurs that results in the formation of lead(II) sulfide (PbS) as a precipitate and nitric acid (HNO3) as a byproduct.
Balanced Chemical Equation:
H2S(g) + Pb(NO3)2 (aq) → PbS(s) ↓ + 2HNO3 (aq)
