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 correctly describes the key characteristics of electrolysis?
- A.Cations migrate to the anode, anions to the cathode, and products form in the electrolyte solution.
- B.Electrons gained at the cathode equal those lost at the anode, only metals are liberated at both electrodes, and AC causes electrolysis.
- C.Cations migrate to the cathode, anions to the anode; products form at electrode surfaces; only hydrogen and metals are liberated at the cathode; mass of substance produced is proportional to electricity passed (Faraday's Law).
- D.Electrolysis occurs with alternating current, non-metals are liberated at the cathode, and the mass of substance produced is independent of electricity passed.
-
2.How is the electrical conductivity of a solution related to its ionic concentration?
- A.Conductivity decreases as ionic concentration increases.
- B.Conductivity is directly proportional to ionic concentration.
- C.Conductivity is independent of ionic concentration.
- D.Conductivity is inversely proportional to ionic concentration.
-
3.Which of the following is NOT a condition for achieving good electroplating?
- A.Using a direct current for the process.
- B.Applying a high current for a short duration.
- C.Thoroughly cleaning the article to be electroplated.
- D.Using an electrolyte with a high concentration of metal ions.
-
4.Complete and balance the following reaction: $$\mathrm{Ag^+} + \underline{\longrightarrow} \longrightarrow \mathrm{Ag}$$
- A.$$1\mathrm{e^-}$$
- B.$$2\mathrm{e^-}$$
- C.$$1\mathrm{H^+}$$
- D.$$1\mathrm{OH^-}$$
-
5.During the electrolysis of molten lead bromide, which of the following takes place?
- A.Bromine is released at the cathode
- B.Lead is deposited at the anode
- C.Bromine ions gain electrons
- D.Lead is deposited at the cathode
