Question

What will we observe on surface of zinc granules when sulphuric acid is added on zinc granules

Answer 1

Hey Troll1478,

Zinc is more reactive than hydrogen and it displaces hydrogen from dilute acids. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. This is a single displacement reaction of a non-metal by a metal.

hope dis helps u!

With regards,

Zn + H₂SO₄ = ZnSO₄ + H₂
