The reaction between strontium chloride (SrCl₂) and sodium sulfate (Na₂SO₄) is a double displacement reaction that produces strontium sulfate (SrSO₄) and sodium chloride (NaCl).

Here's the balanced chemical equation:

SrCl₂ (aq) + Na₂SO₄ (aq) → SrSO₄ (s) + 2 NaCl (aq)

Explanation:

* Strontium chloride (SrCl₂) and sodium sulfate (Na₂SO₄) are both soluble ionic compounds, meaning they dissolve in water to form ions.

* When the solutions are mixed, the strontium ions (Sr²⁺) from SrCl₂ and the sulfate ions (SO₄²⁻) from Na₂SO₄ combine to form strontium sulfate (SrSO₄).

* Strontium sulfate is insoluble in water, so it precipitates out of the solution as a solid.

* The remaining ions, sodium (Na⁺) and chloride (Cl⁻), remain dissolved in the solution as sodium chloride (NaCl).

Note:

* The reaction is considered a precipitation reaction because a solid product forms.

* The reaction is also a metathesis reaction, which involves the exchange of ions between two reactants.
