Question

Assertion (A): Sulphuric acid solution conducts electricity.

Reason (R): Sulphuric acid releases hydroxide ions in solution.

Options

• If both A and R are true, and R is the correct explanation of A.

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

Answer 1

If A is true, but R is false.

Explanation:

The assertion is true because an aqueous solution of sulphuric acid (H₂SO₄) is a strong electrolyte that dissociates into free-moving hydronium (H3O⁺) and sulphate \[\ce{(SO^{2-}_4)}\] ions, which readily conduct electricity. The reason is entirely false because sulphuric acid is a strong acid and releases hydrogen/hydronium ions in water, not hydroxide (OH⁻) ions, which are typically released by bases.
