When an aqueous solution of sodium sulfate (Na₂SO₄) is mixed with an aqueous solution of strontium chloride (SrCl₂), a double displacement reaction occurs, leading to the formation of strontium sulfate (SrSO₄) and sodium chloride (NaCl). The reaction can be represented as follows:
\[
\text{Na}_2\text{SO}_4 (aq) + \text{SrCl}_2 (aq) \rightarrow \text{SrSO}_4 (s) + 2 \text{NaCl} (aq)
\]
In this reaction, strontium sulfate (SrSO₄) is formed, which is typically insoluble in water. Therefore, it will precipitate out of the solution as a solid.
Since a solid precipitate forms, you will observe a visible reaction in the form of white, cloudy precipitation, indicating the formation of strontium sulfate. Thus, a visible reaction will indeed occur when these two solutions are mixed.
