CUET Chemistry Electrochemistry Questions With Solutions 2026

1. Effect of dilution on conductivity of solution:

(a) Increases

(b) Decreases

(c) Unchanged

(d) None of these

Solution: (a) Increases

Explanation: As dilution will increases ions become free to move, improving conductance. Hence, conductivity increases.

2. Which of the options in the following is not a good conductor?

(a) Cu

(b) NaCl (aq)

(c) NaCl (molten)

(d) NaCl (solid)

Solution: (d) NaCl (solid).

Explanation: Solid NaCl lacks free ions, so it cannot conduct electricity.

3. Galvanised iron sheets are coated with:

(a) Carbon

(b) Copper

(c) Zinc

(d) Nickel

Solution: (c) Zinc

Explanation: Zinc coating prevents iron from rusting by forming a protective layer.

4. What is the mixture of Rust?:

(a) FeO & Fe(OH)3

(b) FeO & Fe(OH)2

(c) Fe2O3 & Fe(OH)3

(d) Fe3O4 & Fe(OH)3

Solution: (c) Fe2O3 and Fe(OH)3.

Explanation: Rust mainly contains hydrated ferric oxide and ferric hydroxide.

5. Which of these changes chemical energy into electrical energy?

(a) Galvanic cell

(b) Electrolytic cell

(c) Daniell cell

(d) Both (a) & (c)

Answer: (d) Both (a) & (c)

Explanation: Both the galvanic cell & the Daniell cell can make electricity from chemical reactions. They change stored energy into electric power.

6. When melted salt (NaCl) is broken down by electricity, what forms at the cathode?

(a) Chlorine

(b) Sodium

(c) Sodium mixture

(d) Hydrogen

Answer: (b) Sodium

Explanation: When electricity passes through melted salt, it breaks into sodium and chlorine. Sodium collects at the negative side (cathode).

7. Which one is a rechargeable cell (used more than once)?

(a) Leclanche cell

(b) Lead storage battery

(c) Concentration cell

(d) All of these

Answer: (b) Lead storage battery

Explanation: The lead storage battery can be charged and used again.

That’s why it is called a secondary or rechargeable cell.

8. Which material is used to make a reference electrode?

(a) ZnCl₂

(b) CuSO₄

(c) HgCl₂

(d) Hg₂Cl₂

Answer: (d) Hg₂Cl₂

Explanation: The calomel electrode is a type of reference electrode.

It uses mercury chloride (Hg₂Cl₂) to help measure voltage safely.

9. Why doesn’t galvanized iron rust?

(a) It is coated with copper

(b) Zinc is less reactive

(c) Zinc has stronger protection power

(d) Iron is more reactive than zinc

Answer: (c) Zinc has stronger protection power

Explanation: A zinc layer protects iron from rust. Even if scratched, zinc reacts first and keeps the iron safe from damage.

10. How much oxygen gas is released at room conditions when 9650 coulombs of electricity pass through acidified water?

(a) 1.12 L

(b) 2.24 L

(c) 11.2 L

(d) 22.4 L

Answer: (a) 1.12 L

Explanation: A small amount of current gives off a little oxygen.

With 9650 coulombs, only 1.12 ltrs of oxygen gas is formed.

11. Which chemical is mostly used inside a salt bridge?

(a) K₂SO₄

(b) KNO₃

(c) NaOH

(d) H₂SO₄

Answer: (b) KNO₃

Explanation: Potassium nitrate is used because its ions move easily and keep the cell balanced.

It lets the current flow smoothly.

12. Which one of these can conduct electricity?

(a) Sodium

(b) Diamond

(c) Potassium

(d) Graphite

Answer: (d) Graphite

Explanation: Graphite allows electricity to pass because its electrons can move freely between layers, unlike diamond, which does not conduct.

13. Faraday’s law of electrolysis is related to:

(a) Atomic number of cation.

(b) Speed of cation

(c) Speed of anion

(d) Equivalent weight of electrolyte.

Solution: (d) Equivalent weight of electrolyte.

Explanation: The amount of substance liberated is directly proportional to the quantity of electricity passed.

14. Which of the following is not essential for rusting?

(a) Metal (iron)

(b) Oxygen

(c) Moisture

(d) Light

Solution: (d) Light

Explanation: Rusting only requires oxygen and moisture, not light.

15. Which metal is used to coat iron in order to prevent rusting?

(a) Tin

(b) Copper

(c) Zinc

(d) Nickel

Solution: (c) Zinc

Explanation: Iron is protected from corrosion by galvanization, where it’s coated with zinc.
