What to expect: This mock test covers key concepts from the Analytical Chemistry chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Which of the following correctly describes the test for detecting carbonate ions in a salt, including the observations and the expected outcome?
- A.Add dilute sulphuric acid to the salt; a colourless, odourless gas evolves with brisk effervescence and turns lime water milky.
- B.Add sodium hydroxide to the salt; a pungent gas evolves and turns red litmus blue.
- C.Heat the salt strongly; a brown gas evolves and turns acidified potassium dichromate green.
- D.Add silver nitrate solution to the salt; a white precipitate forms that dissolves in ammonia.
-
2.Which gas decolorises potassium permanganate (KMnO₄) solution?
- A.Sulphur dioxide
- B.Ammonia
- C.Hydrogen chloride
- D.Carbon dioxide
-
3.Detection of Sulphide: On adding dilute Sulphuric acid to metallic Sulphide, a colourless gas having rotten egg smell evolves which turns lead acetate solution black. Which of the following sets of balanced chemical equations correctly represents the reactions involved?
- A.FeS + H₂SO₄(dil.) → FeSO₄ + H₂S↑; (CH₃COO)₂Pb + H₂S → 2CH₃COOH + PbS↓
- B.FeS + H₂SO₄(dil.) → FeSO₃ + H₂S↑; (CH₃COO)₂Pb + H₂S → PbSO₄ + 2CH₃COOH
- C.FeS + 2HCl → FeCl₂ + H₂S↑; (CH₃COO)₂Pb + H₂S → PbCl₂ + 2CH₃COOH
- D.FeS + H₂SO₄(dil.) → Fe₂(SO₄)₃ + H₂S↑; (CH₃COO)₂Pb + H₂S → PbO + 2CH₃COOH
-
4.Detection of Hydrogen: On reaction of active metals with dilute acids, a colourless and odourless gas evolves which burns with a popping sound. Which of the following represents the correct balanced chemical equations for the reactions involving magnesium and zinc with hydrochloric acid?
- A.Mg + HCl → MgCl₂ + H₂ and Zn + HCl → ZnCl₂ + H₂
- B.Mg + 2HCl → MgCl₂ + H₂↑ and Zn + 2HCl → ZnCl₂ + H₂↑
- C.Mg + HCl → MgCl + H and Zn + HCl → ZnCl + H
- D.2Mg + HCl → Mg₂Cl + H₂ and 2Zn + HCl → Zn₂Cl + H₂
-
5.Which gas decolourises potassium permanganate solution?
- A.Oxygen
- B.Sulphur dioxide
- C.Nitrogen
- D.Carbon dioxide
