The reaction between ammonium sulfate ((NH₄)₂SO₄) and potassium hydroxide (KOH) is a double displacement reaction that produces ammonia (NH₃), potassium sulfate (K₂SO₄), and water (H₂O).

Here's the balanced chemical equation:

(NH₄)₂SO₄(aq) + 2KOH(aq) → 2NH₃(g) + K₂SO₄(aq) + 2H₂O(l)

Explanation:

* (NH₄)₂SO₄(aq): Ammonium sulfate is dissolved in water (aqueous solution).

* 2KOH(aq): Two moles of potassium hydroxide are dissolved in water.

* 2NH₃(g): Two moles of ammonia gas are produced.

* K₂SO₄(aq): Potassium sulfate is dissolved in water.

* 2H₂O(l): Two moles of water are produced in liquid form.

Key points about the reaction:

* The reaction is exothermic, meaning it releases heat.

* The ammonia gas produced is responsible for the characteristic pungent odor.

* The reaction is often used in laboratory settings to prepare ammonia gas.
