Bronsted – Lowry concept of acid and base

According to Bronsted-Lowry, an acid can be defined as any substance (molecule or ion) that has the tendency to donate a proton (H⁺ ) to any substance whereas a base can be defined as any substance (molecule or ion) that has the tendency to accept a proton (H⁺) from any other substance.

Conjugate acid-base pair

The residual part of acid after losing a proton will have a tendency to accept a proton (H⁺). Therefore, it will behave as a base. These pairs of substances which differ from one another by a proton (H⁺) are known as conjugate acid-base pairs. Consider a general example of an acid:

Prediction of the products

Bronsted-Lowry acid is a proton (H⁺) donor while Bronsted-Lowry base is a proton (H⁺) acceptor.
