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.The salt which gives a dirty green precipitate with sodium hydroxide solution is
- a.iron (III) sulphate
- b.iron (II) chloride
- c.iron (II) sulphate
- d.iron (III) chloride
-
2.Why is the alkali added drop by drop to the salt solution?
- A.To prevent missing a precipitate that redissolves in excess alkali.
- B.To increase the concentration of the alkali for faster reaction.
- C.To avoid splashing and ensure the solution remains clear.
- D.To reduce the volume of alkali required for the reaction.
-
3.Assertion: Ferrous chloride reacts with ammonium hydroxide to form a dirty green precipitate. Reason: Ferrous hydroxide is green and turns brown on oxidation. (a) Both Assertion and Reason are true and Reason is the correct explanation for Assertion (b) Both Assertion and Reason are true, but Reason is not the correct explanation for Assertion. (c) Assertion is true, but Reason is false. (d) Assertion is false, but Reason is true.
- A.Both Assertion and Reason are true and Reason is the correct explanation for Assertion
- B.Both Assertion and Reason are true, but Reason is not the correct explanation for Assertion
- C.Assertion is true, but Reason is false.
- D.Assertion is false, but Reason is true.
-
4.Which of the following correctly describes the test for detecting sulphite ions in a salt, including the observations and relevant chemical reaction?
- A.Add dilute sulphuric acid to the salt; a colourless gas with a burning sulphur smell evolves, turning acidified potassium dichromate solution green and decolourizing potassium permanganate solution.
- B.Add sodium hydroxide to the salt; a pungent gas evolves, turning red litmus blue and forming a white precipitate with calcium chloride solution.
- C.Add concentrated hydrochloric acid to the salt; a yellow gas evolves, turning starch-iodide paper blue and forming a black precipitate with lead acetate solution.
- D.Add barium chloride solution to the salt; a white precipitate forms, which dissolves in dilute hydrochloric acid with effervescence of carbon dioxide gas.

5.Match the columns A with Column B:
(a) 1-C, 2-B, 3-B, 4-D (b) 1-D, 2-A, 3-B, 4-C (c) 1-B, 2-C, 3-D, 4-A (d) 1-D, 2-A, 3-C, 4-BColumn A Column B (1) Pb²⁺ (A) Reddish brown (2) Fe²⁺ (B) White insoluble in excess (3) Zn²⁺ (C) Dirty green (4) Fe³⁺ (D) White soluble in excess
