Sample questions
-
1.Which chloride of a metal is soluble in excess of ammonium hydroxide, and what is the balanced chemical equation for this reaction?
- A.Copper(II) chloride; CuCl₂ + 4NH₄OH → [Cu(NH₃)₄]Cl₂ + 4H₂O
- B.Silver chloride; AgCl + 2NH₄OH → [Ag(NH₃)₂]Cl + 2H₂O
- C.Zinc chloride; ZnCl₂ + 4NH₄OH → [Zn(NH₃)₄]Cl₂ + 4H₂O
- D.Aluminium chloride; AlCl₃ + 3NH₄OH → Al(OH)₃ + 3NH₄Cl
-
2.A solution of zinc nitrate is treated with sodium hydroxide drop by drop. Which of the following correctly describes the observations and the reactions involved?
- A.A white precipitate of zinc hydroxide forms initially, which dissolves in excess sodium hydroxide to form sodium zincate.
- B.A blue precipitate forms initially, which remains insoluble even in excess sodium hydroxide.
- C.No precipitate forms; the solution remains clear as zinc nitrate reacts to form a soluble complex immediately.
- D.A white precipitate forms initially, which turns brown on adding excess sodium hydroxide.
-
3.A solution which gives dirty green precipitate with sodium hydroxide likely to have
- A.Zn²⁺ ions
- B.Fe²⁺ ions
- C.NH₄⁺ ions
- D.Cu²⁺ ions
-
4.Detection of Carbonate: On adding dilute Sulphuric acid to a metallic Carbonate, a colourless and odourless gas evolves which turns lime water milky. Which of the following sets of balanced chemical equations correctly represents the reactions involved?
- A.Na₂CO₃ + H₂SO₄ → Na₂SO₄ + H₂O + CO₂; Ca(OH)₂ + CO₂ → CaCO₃ + H₂O
- B.Na₂CO₃ + H₂SO₄ → Na₂SO₄ + H₂ + CO₃; Ca(OH)₂ + CO₃ → CaCO₃ + H₂O
- C.Na₂CO₃ + H₂SO₄ → Na₂S + H₂O + CO₂; Ca(OH)₂ + CO₂ → CaO + H₂CO₃
- D.Na₂CO₃ + H₂SO₄ → Na₂O + H₂SO₄ + CO₂; Ca(OH)₂ + CO₂ → Ca(HCO₃)₂
-
5.(c) A metal which produces hydrogen on reacting with alkali as well as with acid.
- i.Iron
