Question

Ammonia, NH3, acts as an Arrhenius base because it Ammonia, N H 3, acts as an Arrhenius base because it blank the concentration of hydroxide ion, \rm OH^-, in aqueous solution. the concentration of hydroxide ion, OH−, in aqueous solution.

Answer 1

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.
