When an aqueous solution of lithium chloride (LiCl) is mixed with an aqueous solution of ammonium sulfate ((NH₄)₂SO₄), a double displacement reaction occurs. This reaction results in the formation of lithium sulfate (Li₂SO₄) and ammonium chloride (NH₄Cl).

Here's the balanced chemical equation for the reaction:

2LiCl(aq) + (NH₄)₂SO₄(aq) → Li₂SO₄(aq) + 2NH₄Cl(aq)

Explanation:

* Double Displacement: The positive and negative ions of the reactants switch partners.

* Aqueous Solutions: Both LiCl and (NH₄)₂SO₄ are soluble in water, meaning they dissociate into their ions.

* Product Formation: Lithium sulfate (Li₂SO₄) is also soluble in water, while ammonium chloride (NH₄Cl) is soluble as well. This means that all products remain dissolved in the solution.

Important Note: There is no precipitate (solid) formed in this reaction.

Therefore, when you mix aqueous solutions of lithium chloride and ammonium sulfate, you essentially end up with a mixture containing lithium sulfate and ammonium chloride in solution. No visible change occurs.
