When sodium sulfate (Na₂SO₄) reacts with barium chloride (BaCl₂), a double displacement reaction occurs, resulting in the formation of barium sulfate (BaSO₄), which is insoluble in water, and sodium chloride (NaCl). The balanced chemical equation for this reaction is:
\[ \text{Na}_2\text{SO}_4 (aq) + \text{BaCl}_2 (aq) \rightarrow \text{BaSO}_4 (s) + 2 \text{NaCl} (aq) \]
In this reaction:
- Na₂SO₄ is aqueous (dissolved in water).
- BaCl₂ is also aqueous.
- BaSO₄ precipitates out as a solid (indicated by (s)).
- NaCl remains in the aqueous solution.
