Towards metals, dilute H₂SO₄ acts as a typical acid, while hot concentrated H₂SO₄ acts as an oxidising agent as well as an acid. Which of the following metals produces H₂ with dilute H₂SO₄ but SO₂ with hot concentrated H₂SO₄?
Options:
Answer:
B
Solution:
Zn + dil. H₂SO₄ → ZnSO₄ + H₂↑; Zn + 2H₂SO₄(conc., hot) → ZnSO₄ + SO₂↑ + 2H₂O. Cu reacts only with the conc. acid; Au and Pt do not react at all.
