According to the Bronsted-Lowry theory, an acid is a proton donor, and a base is a proton acceptor, and an acid-base reaction occurs when an acid donates a proton to a base. The theory also created the concept of conjugate acid-base pairs, which are used to describe Bronsted-Lowry acid-base reactions. They also stated that, the stronger the acid, the weaker is its conjugate base, the weaker the acid, the stronger is its conjugate base. Finally, water can act as an acid or as a base, depending on the other reactant.
