Sample questions
-
1.A solution of lead nitrate is treated with ammonium hydroxide drop by drop. Which of the following correctly describes the observations and the balanced chemical equation for the reaction?
- A.A white precipitate of lead hydroxide forms, insoluble in excess ammonium hydroxide. Equation: Pb(NO₃)₂ + 2NH₄OH → Pb(OH)₂↓ + 2NH₄NO₃
- B.A blue precipitate of lead hydroxide forms, soluble in excess ammonium hydroxide. Equation: Pb(NO₃)₂ + NH₄OH → Pb(OH)↓ + NH₄NO₃
- C.No precipitate forms; the solution remains clear. Equation: Pb(NO₃)₂ + 2NH₄OH → Pb(NH₄)₂ + 2NO₃OH
- D.A white precipitate of lead oxide forms, soluble in excess ammonium hydroxide. Equation: Pb(NO₃)₂ + 2NH₄OH → PbO↓ + 2NH₄NO₃ + H₂O
