* Sulfuric acid is a strong acid: This means it completely ionizes in water, releasing hydrogen ions (H⁺).
* Ammonia is a weak base: This means it only partially ionizes in water, accepting protons (H⁺) to form ammonium ions (NH₄⁺).
When sulfuric acid and ammonia react, the following reaction occurs:
H₂SO₄ + 2NH₃ → (NH₄)₂SO₄
This reaction forms ammonium sulfate ((NH₄)₂SO₄), a salt. While ammonium ions (NH₄⁺) can act as a weak acid, the reaction of a strong acid and a weak base results in an acidic solution.
Therefore, the final solution will be acidic.
