Mar 30 2020 · By the Arrhenius definition Acids release a proton or H in water. Bases release a hydroxide ion OH - in water. As stated previously the Arrhenius theory definition of acids and bases is the narrowest since it only discusses aqueous solutions. To be able to define more reactions the Brønsted-Lowry definition focuses on proton transfer.

According to this definition an acid is an electron pair acceptor and a base is an electron pair donor. Therefore a Lewis acid can be defined as a chemical entity that can accept a pair of electrons from a Lewis base to form a coordinate covalent bond with it.

This definition proved sufficient for over 50 years until the advent of Svante Arrhenius. In fact it is still compatible with modern definitions. Liebig had no corresponding theoretical definition for bases. There were still identified in an empirical fashion as substances which neutralized acids. However no one could explain why they did so.

Acids and bases are two special kinds of chemicals. Almost all liquids are either acids or bases to some degree. Whether a liquid is an acid or base depends on the type of ions in it. If it has a lot of hydrogen ions then it is an acid. If it has a lot of hydroxide ions then it is a base.

In other words a Lewis acid is an electron-pair acceptor. A Lewis base is any substance such as the OHion that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor. One advantage of the Lewis theory is the way it complements the model of oxidation-reduction reactions.
