Is NH3 a Bronsted-Lowry base?

May 11, 2017

${\text{NH}}_{3}$ is a Brønsted-Lowry base.

Explanation:

A Brønsted-Lowry base is a substance that behaves as a proton acceptor.

For example,

underbrace("NH"_3)_color(red)("proton acceptor") + "H-Cl" → "NH"_4^"+" + "Cl"^"-"

The ${\text{NH}}_{3}$ is accepting a proton from the $\text{HCl}$, so it is behaving as a Brønsted-Lowry base.
