MCQ
Which solution gives a white precipitate with excess ammonium hydroxide solution.
- ACopper nitrate
- BIron [II] sulphate
- CIron [III] chloride
- ✓Lead nitrate
✓
Answer
Correct option: D.
Lead nitrate
(d) Lead nitrate
Explanation : When you add excess ammonium hydroxide to a solution of lead nitrate (Pb(NO3)2), it forms a white precipitate of lead(II) hydroxide :
The white precipitate is lead(II) hydroxide, which is insoluble in water. This is a characteristic reaction of lead(II) salts with excess ammonium hydroxide.
