WebThe basicity of amines is often discussed indirectly in terms of the acidity of their respective conjugate acids. Recall that the conjugate acid of a weak base (e.g. like water) is a strong acid (like hydronium ion), while the conjugate acid of a strong base (like hydroxide ion) is a weak acid (like water). WebIn the Brønsted–Lowry definition of acids and bases, a conjugate acid–base pair consists of two substances that differ only by the presence of a proton (H⁺).
