Na3PO4 is soluble and exists in three units of the cation Na+ and one unit of the anion PO4^3-. The conjugate acid of this anion is HP04^2-.
According to the Brnsted-Lowry acid-base theory, a conjugate acid is a chemical that is produced when an acid donates a proton (H +) to a base; in other words, it is a base that has had a hydrogen ion added to it, as in the opposite reaction, the base loses a hydrogen ion. A base is made when a proton from an acid is taken on, while an acid is produced when a base accepts one. An acid and a base that only differ by the presence or absence of a proton are said to be conjugate acid-base pairs.
