How to balance it, step by step
- Count each element on both sides. Every count already matches, so no coefficients are needed.
- Check: Zn 1 = 1, H 2 = 2, S 1 = 1, O 4 = 4. Balanced.
What happens
It is a displacement reaction: a more reactive element pushes a less reactive one out of its compound. Zinc granules in dilute sulphuric acid give zinc sulphate and bubbles of hydrogen gas.
Zinc and sulphuric acid: quick answers
What is the balanced equation for zinc and sulphuric acid?
Zn(s) + H₂SO₄(aq) → ZnSO₄(aq) + H₂(g). It is already balanced as written, so every coefficient is 1. Each side then has 1 Zn, 2 H, 1 S and 4 O.
