Answer:
Ammonia acts as an Arrhenius base because it increases the concentration of OH⁻ in aqueous solution.
Explanation:
The acid-base theory of Arrhenius explains that in aqueous solutions both acid and base dissociate, releasing ions in the solution. The acid release the ion H⁺ and some anion, and the base release the ion OH⁻ and some cation.
In water, the reaction of ammonia is:
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻
Because of that, ammonia is an Arrhenius base.
