The theories of acids and bases
Arrhenius theoryAn acid is a compound that can release hydrogen ions (H+) in aqueous solution.
A base is a compound that can yield hydroxide ions (OH-) in aqueous solution. |
Brønsted-Lowry theory
A BL acid is a hydrogen-ion donor substance.
A BL base is a hydrogen-ion acceptor substance. This theory encompasses the Arrhenius theory. |
Lewis theoryA Lewis acid is a substance that can accept a pair of electrons to form a covalent bond.
A Lewis base is a substance that can donate a pair of electrons to form a covalent bond. It encompasses the Brønsted-Lowry theory. |
