As you might expect based on their definition of an acid, Brpnsted and Lowry defined a base as a proton acceptor. In the reaction taking place in Figure 8, ammonia, NH3, serves as the proton acceptor and is therefore a Brunsted-Lowry base. Ammonia also functions as a proton acceptor when it dissolves in water, as in the equation below.
