Sample questions
-
1.How can ammonium hydroxide solution be used to distinguish between Zn²⁺ and Pb²⁺ ions?
- A.Both form white precipitates that dissolve in excess ammonium hydroxide.
- B.Zn²⁺ forms a white precipitate soluble in excess; Pb²⁺ forms an insoluble white precipitate.
- C.Zn²⁺ forms a blue precipitate; Pb²⁺ forms a white precipitate.
- D.Both ions form colored precipitates insoluble in excess ammonium hydroxide.
-
2.Which chemical test correctly distinguishes between calcium nitrate solution and zinc nitrate solution?
- A.Add NaOH; calcium nitrate forms a precipitate insoluble in excess, zinc nitrate forms a precipitate soluble in excess.
- B.Add NH₄OH; calcium nitrate forms white precipitates of Ca(OH)₂, zinc nitrate forms gelatinous precipitates of Zn(OH)₂ soluble in excess.
- C.Add HCl; calcium nitrate forms a gas, zinc nitrate forms a precipitate.
- D.Add AgNO₃; calcium nitrate forms a white precipitate, zinc nitrate forms no precipitate.
-
3.... is used as an analytical reagent to identify metal ions in qualitative analysis.
- A.Ammonium Sulphate
- B.Ammonium Chloride
- C.Ammonium Carbonate
- D.Ammonium Hydroxide
-
4.What observation is made when ammonium hydroxide is first added in a small quantity and then in excess to a solution of copper sulphate?
- A.White precipitate forms, dissolving in excess to give a colorless solution.
- B.Blue precipitate forms, dissolving in excess to give a deep blue solution.
- C.Green precipitate forms, remaining insoluble in excess.
- D.No precipitate forms; solution turns pale blue throughout.
-
5.Aqueous solution of copper sulphate reacts with aqueous ammonium hydroxide solution to give
- A.brown ppt.
- B.white ppt.
- C.pale blue ppt.
- D.green ppt.
