Question

What is the bronsted lowry definition of an acid

Answer 1

The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923.

Answer 2

Explanation:

According to Bronsted-Lowry, acids are the species that donate protons or $(H^{+})$.

For example, HCl is a Bronsted-Lowry acid as it releases protons upon dissociation.

                   $HCl \rightarrow H^{+} + Cl^{-}$

On the other hand, species that take up or accept a protons or $(H^{+})$ are known as Bronsted-Lowry base.

For example, $NH_{3} + H^{+} \rightarrow NH^{+}_{4}$

Therefore, $NH_{3}$ is a Bronsted-Lowry base as it accepts a proton.
