The first of these was proposed in 1923 by the Danish chemist Johannes Brønsted and the English chemist Thomas Lowry, and has come to be known as the Brønsted-Lowry definition of acidity and basicity.

Notice, for example, the difference in acidity between phenol and cyclohexanol.

This is a big step: we are, for the first time, taking our knowledge of organic structure and applying it to a question of organic reactivity.

Complex ions are examples of Lewis acid-base adducts. In a complex ion, we have a central atom, often consisting of a transition metal cation, which acts as a Lewis acid, and several neutral molecules or ions surrounding them called ligands that act as Lewis bases. Complex ions form by sharing electron pairs to form coordinate covalent bonds.

It must have a pair of electrons available to share with another atom to form a bond. The most readily available electrons are those that are not already in bonds. Bonding electrons are low in energy. Non-bonding electrons are higher in energy and may be stabilized when they are delocalized in a new bond.

Lewis acids are electron pair acceptors, while Lewis bases are donors. This concept explains reactions like the classic example between borane BH3 and NH3, resulting in a coordinate covalent bond. The Usanovich acid-base concept extends this by including oxidation-reduction reactions.
