Which salt is formed when zinc reacts with dilute sulphuric acid?
Answer and explanation
Correct answer: Zinc sulphate
Zinc reacts with dilute sulphuric acid in a single-displacement reaction: Zn + H₂SO₄ → ZnSO₄ + H₂. The zinc replaces hydrogen in the acid, forming zinc sulphate, while hydrogen gas is liberated. Therefore, option D is correct. Zinc chloride would require hydrochloric acid, zinc carbonate would involve a carbonate source, and sodium sulphate contains sodium rather than zinc. The acid radical helps identify the salt’s name.
