Explanation:
According to Bronsted-Lowry, acids are the species that donate protons or [tex](H^{+})[/tex].
For example, HCl is a Bronsted-Lowry acid as it releases protons upon dissociation.
[tex]HCl \rightarrow H^{+} + Cl^{-}[/tex]
On the other hand, species that take up or accept a protons or [tex](H^{+})[/tex] are known as Bronsted-Lowry base.
For example, [tex]NH_{3} + H^{+} \rightarrow NH^{+}_{4}[/tex]
Therefore, [tex]NH_{3}[/tex] is a Bronsted-Lowry base as it accepts a proton.
