Conjugate acid

In the Brønsted-Lowry (protonic) theory of acids and bases, a conjugate acid is the acid member, HX, of a pair of two compounds that transform into each other by gain or loss of a proton. The base produced, X^-, is called the conjugate base.

H₃PO₄ Phosphoric acid H₂PO₄^- Dihydrogen phosphate ion

HC₂H₃O₂ Acetic acid C₂H₃O₂^- Acetate ion

H₂CO₃ Carbonic acid HCO₃^- Hydrogen carbonate ion

H₂S Hydrosulfuric acid HS^-

H₂PO₄^- Dihydrogen phosphate ion HPO₄⁺ Hydrogen phosphate ion
