Conjugate (acid-base theory)

Common card · No. 390165

A conjugate acid is a chemical compound that is formed when an acid gives a proton (H+) to a base. A conjugate base is what remains after an acid has donated a proton during a chemical reaction. In other words, a conjugate acid is a base with a hydrogen ion added to it, as it loses a hydrogen ion in the reverse reaction, and a conjugate base is a substance formed by the removal of a proton from an acid, as it can gain a hydrogen ion in the reverse reaction. Because some acids can give multiple protons, the conjugate base of an acid may itself be acidic. In summary, this interaction can be represented as the following chemical reaction: acid + base ⇌ conjugate base + conjugate acid Johannes Nicolaus Brønsted and Martin Lowry introduced the Brønsted–Lowry acid–base theory, which says that any compound that can give a proton to another compound is an acid, and the compound that receives the proton is a base. (A proton is a subatomic particle with a positive electrical charge in the nucleus...
