Quick revision

Class 9 Chemistry MCQs Qualitative Analysis are one of the fastest ways to improve your board exam performance — especially when you practice with purpose, revise weak concepts, and learn from explanations.

On Prepzy, you can practice 21 MCQs from “Qualitative Analysis” in Chemistry for FBISE. Each question is designed to mirror the style, wording, and concept-testing approach used in Pakistani board papers.

Use this chapter page to revise definitions, formulas, and key ideas, then attempt the MCQs in small sets. Track patterns in your mistakes: is it a concept gap, a calculation error, or a misread statement? Fixing the pattern is what raises your score.

If you’re preparing for matric / SSC Part exams, focus on understanding the concept first, then speed. MCQs reward clarity — not memorization. A clear concept turns into fast correct answers.

What to focus on

  • Primary focus: Qualitative Analysis concepts tested in Class 9 Chemistry
  • Practice with instant answer-checking to reduce repeated mistakes
  • Revise common definitions, units, and standard results before timed practice
  • Aim for accuracy first, then build speed with short quizzes

Study tips

  • Read the question stem first, then scan options for distractors (near-correct choices).
  • If the chapter is formula-heavy, write a mini-formula sheet and revise it before every attempt.
  • After each practice set, re-attempt only the wrong MCQs to convert weak areas into strengths.
  • Mix easy + medium MCQs for momentum, then finish with hard questions for exam readiness.

    • Carbon dioxide
    • Chlorine
    • Ammonia
    • Sulphur dioxide
    Answer & explanation

    Correct: Ammonia

    Red litmus paper turns blue in the presence of a basic gas like ammonia.

  7. 7. What happens to metal ions in the flame during a flame test?

    • They become excited and emit light
    • They turn into gas
    • They lose mass
    Answer & explanation

    Correct: They become excited and emit light

    The heat from the flame causes metal ions to become excited, and as they return to their ground state, they emit light.

  8. 8. What does the reaction CaCO3 + HCl produce?

    • Water
    • Lime water
    • Carbon dioxide
    • Sulphur dioxide
    Answer & explanation

    Correct: Carbon dioxide

    The reaction produces carbon dioxide gas along with calcium chloride and water.

    • Golden yellow
    • Crimson red
    • Purple
    • Blue
    Answer & explanation

    Correct: Purple

    Potassium gives a purple flame color in a flame test.

  10. 10. What happens to blue litmus paper when exposed to chlorine gas?

    • Turns green
    • Turns red then white
    • Remains unchanged
    • Turns blue again
    Answer & explanation

    Correct: Turns red then white

    Chlorine gas causes blue litmus paper to turn red due to its acidic nature and then bleaches it to white.

  11. 11. What is used to hold the sample solution during the flame test?

    • Glass beaker
    • Bunsen burner
    • Wire loop
    • Evaporating dish
    Answer & explanation

    Correct: Wire loop

    A clean, non-reactive wire loop is used to hold the sample solution during the flame test.

  12. 12. How is hydrogen gas generated for detection?

    • Reaction of zinc with hydrochloric acid
    • Reaction of zinc with sulphuric acid
    • Reaction of zinc with oxygen
