What is a Brønsted-Lowry base?

A Brønsted-Lowry base is a substance that can accept a proton (H⁺ ion) in a chemical reaction, according to the Brønsted-Lowry theory of acids and bases. This definition is widely used in chemistry because it extends the concept of bases beyond those that contain the hydroxide ion, thus including a broader range of compounds. For example, ammonia (NH₃) acts as a Brønsted-Lowry base when it accepts a proton to form ammonium (NH₄⁺). Understanding Brønsted-Lowry bases is essential for IB Chemistry students as it helps them grasp acid-base reactions, pH changes, and related equilibria in aqueous solutions.
