Question

What happens when dilute sulphuric acid is poured on zinc granules?

Answer 1

when zinc reacts with dilute sulphuric acid hydrogen gas is evolved, with an effervescence.
Zn +H2SO4 --->ZnSO4+H2

Answer 2

When dilute Sulphuric acid is poured on zinc granules following reaction occurs:

           Zn + H₂SO₄ ⇒ ZnSO₄ + H₂

• When dilute sulphuric acid is poured on zinc granules, Zinc sulfate is formed along with the evolution of H₂ gas.
• When a metal reacts with the acid, it liberates H₂ gas and forms metallic salt.
• Due to this, when zinc reacts with H₂SO₄ it liberates H₂ gas and forms a metallic salt ZnSO₄.
• So, the balanced chemical equation for this is

              Zn + H₂SO₄ ⇒ ZnSO₄ + H₂

Hence, when dilute Sulphuric acid is poured on zinc granules, zinc sulfate is formed along with the evolution of H₂ gas.
