The Bronsted-Lowry acid base theory is a theory in science founded by Joahnnes Nicolaus Bronsted and Thomas Martin Lowry. They founded this theory in 1923. The theory means that when an acid and a base come together to react, then two things happen.

First, the acid creates its own conjugate base and the base creates its own conjugate acid. The term “conjugate” refers to the appearance of H+ ion. With the Bronsted-Lowry acid, what takes place is the substance can donate a proton H+ ion to a base. With this theory, there are other factors that take place including the aqueous solutions involved in the acid-base theory as well as atmospheric substances that could be non-aqueous solutions. Some comparisons have been made with this theory.

Any substance that can donate a proton, H+ ion to a base.

B is the correct answer since : A: Is the definition for a Arrhenius acid - Any substance that ionizes when it dissolves in water to give the H+ ion. C: Is the definition of a Lewis base - Any substance that can donate a pair of nonbonding electrons.
