When water acts as a base, it becomes H3O+, which is an acid and is called the conjugate acidconjugate acidA conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid donates a proton (H+) to a base—in other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion.https://en.wikipedia.org › wiki › Conjugate_acidConjugate acid – Wikipedia of water.
