Free online mock test for Electrolysis (ICSE Class 10 Chemistry) — 20 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Electrolysis 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 substances would conduct electricity? (i) Tap water (ii) Dry common salt (iii) Liquid oxygen (iv) Aqueous sugar solution (v) Sulphuric acid containing 100% by mass of sulphuric acid.
-
2.Complete the following table:
Electrolyte Cathode Anode Product at cathode Product at anode Dil. sulphuric acid Platinum Platinum CuSO₄ solution Copper Copper CuSO₄ solution Platinum Platinum -
3.Differentiate between metallic conductors and electrolytic conductors based on the following aspects: flow of current, state of conduction, and chemical change during conduction. Which of the following correctly summarizes these differences?
- A.Metallic conductors involve electron flow in solid/liquid states with no chemical change, while electrolytic conductors involve ion flow in aqueous/molten states with chemical changes.
- B.Metallic conductors involve ion flow in solid state with chemical changes, while electrolytic conductors involve electron flow in molten state with no chemical changes.
- C.Metallic conductors conduct only in liquid state with chemical changes, while electrolytic conductors conduct in solid state with electron flow and no chemical changes.
- D.Metallic conductors involve electron flow in aqueous solutions with chemical changes, while electrolytic conductors involve ion flow in solid state with no chemical changes.
-
4.The electrolysis of acidified water is an example of:
- A.Reduction
- B.Oxidation
- C.Redox reaction
- D.Synthesis
-
5.Differentiate between strong electrolytes and weak electrolytes based on the following criteria. Which of the given options correctly represents their characteristics? 1. Conductivity 2. Degree of dissociation 3. State of particles in solution 4. Example of bulb glow
- A.Strong electrolytes are poor conductors, partially dissociated, contain mostly molecules, and cause dim bulb glow. Weak electrolytes are good conductors, fully dissociated, contain only ions, and cause bright bulb glow.
- B.Strong electrolytes are good conductors, almost fully dissociated, contain mostly free ions, and cause bright bulb glow. Weak electrolytes are poor conductors, partially dissociated, contain both ions and molecules, and cause dim bulb glow.
- C.Strong electrolytes conduct no electricity, remain undissociated, contain only molecules, and cause no bulb glow. Weak electrolytes conduct moderately, dissociate fully, contain only ions, and cause moderate bulb glow.
- D.Strong electrolytes are good conductors, partially dissociated, contain both ions and molecules, and cause dim bulb glow. Weak electrolytes are poor conductors, fully dissociated, contain only ions, and cause bright bulb glow.
