How to balance it, step by step
- Count the atoms of each element on both sides, as written.
- Start with the biggest formula, H₂SO₄: put 1 in front of it.
- S: 1 on the left. Put 1 in front of BaSO₄.
- Ba: 1 on the right. Put 1 in front of Ba(OH)₂.
- H: 4 on the left. Put 2 in front of H₂O (2 × 2 = 4).
- Check: H 4 = 4, S 1 = 1, O 6 = 6, Ba 1 = 1. Balanced.
What happens
It is a neutralisation reaction: an acid, or an acidic oxide, reacts with a base to give a salt and water. The acid and the base neutralise each other, and the salt barium sulphate comes out as a white precipitate.
Sulphuric acid and barium hydroxide: quick answers
What is the balanced equation for sulphuric acid and barium hydroxide?
H₂SO₄(aq) + Ba(OH)₂(aq) → BaSO₄(s) + 2 H₂O(l). The coefficients are 1, 1, 1 and 2. Each side then has 4 H, 1 S, 6 O and 1 Ba.

How do you balance H₂SO₄ + Ba(OH)₂ → BaSO₄ + H₂O?
Start with the biggest formula, H₂SO₄: put 1 in front of it. S: 1 on the left. Put 1 in front of BaSO₄. Ba: 1 on the right. Put 1 in front of Ba(OH)₂. H: 4 on the left. Put 2 in front of H₂O (2 × 2 = 4). Never change a subscript, because that would change the substance.
