ICSE Class 10 Chemistry sample papers and practice questions

Sample papers work best after you have revised each chapter. Below are a few Chemistry MCQs with answers to check yourself. LerkAI can then create a full practice paper in your board's style for any mix of the 12 chapters, time you, and explain every wrong answer. These are practice papers made by LerkAI, not official ICSE papers, so also solve your board's official sample papers.

Practice questions with answers

  1. The number of moles in 22 g of CO₂ is:

    Answer: 0.5. Molar mass of CO₂ = 44 g, so 22 ÷ 44 = 0.5 mol.

  2. Which gas turns moist red litmus blue?

    Answer: NH₃. Ammonia is basic, so it turns moist red litmus blue.

  3. During electrolysis, cations move towards the:

    Answer: Cathode. Cations are positive, so they move to the negative electrode, the cathode.
