Formation: When an acid donates a proton, it forms its conjugate base; when a In an acid–base reaction, an acid plus a base reacts to form a conjugate base plus a conjugate acid: Conjugates are formed when an acid loses a hydrogen proton or a base gains a hydrogen proton. Hence, a conjugate base is a substance formed b When an acid dissociates into its ions in water, it loses a When an acid engages in a reaction, it transforms into a new chemical species. Reverse A conjugate acid is the particle formed when a base accepts a proton, while a conjugate base is what remains after an acid has donated its proton. Conjugate bases behave like bases by If an acid is strong, it readily donates its proton, meaning its conjugate base has a very low tendency to accept a proton back, making it a weak base. In 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⁺).
