How to balance it, step by step
- Count the atoms of each element on both sides, as written.
- Start with the biggest formula, Na₂SO₄: put 1 in front of it.
- Na: 2 on the left. Put 2 in front of NaCl.
- Cl: 2 on the right. Put 1 in front of BaCl₂ (1 × 2 = 2).
- Ba: 1 on the left. Put 1 in front of BaSO₄.
- Check: Ba 1 = 1, Cl 2 = 2, Na 2 = 2, S 1 = 1, O 4 = 4. Balanced.
What happens
It is a double displacement reaction: two compounds swap their ions. A white precipitate of barium sulphate forms at once as the two salts swap their ions.

How do you balance BaCl₂ + Na₂SO₄ → BaSO₄ + NaCl?
Start with the biggest formula, Na₂SO₄: put 1 in front of it. Na: 2 on the left. Put 2 in front of NaCl. Cl: 2 on the right. Put 1 in front of BaCl₂ (1 × 2 = 2). Ba: 1 on the left. Put 1 in front of BaSO₄. Never change a subscript, because that would change the substance.
