There are three definitions for acids and bases that you must be familiar with Arrhenius, Brousted-Lowry, and Lewis. In the following section, you will review the meaning and application of these different definitions. 

In the Arrhenius definitions for acids and bases, the strength of the acid or base is determined by the degree of ionization. For example, HC1 is considered a strong acid because when it is placed in water it completely ionizes to H+ and Cl-. The strongest acids and bases are all Arrhenius acids and bases. 

Feb. 19,1859, Wijk, Sweden - Oct. 2,1927, Stockholm, Sweden). Arrhenius developed the theory of dissociation of electrolytes in solutions that was first formulated in his Ph.D. thesis in 1884 Recherches sur la conductibilit galvanique des dectrolytes (Investigations on the galvanic conductivity of electrolytes). The novelty of this theory was based on the assumption that some molecules can be split into ions in aqueous solutions. The - conductivity of the electrolyte solutions was explained by their ionic composition. In an extension of his ionic theory of electrolytes, Arrhenius proposed definitions for acids and bases as compounds that generate hydrogen ions and hydroxyl ions upon dissociation, respectively (- acid-base theories). For the theory of electrolytes Arrhenius was awarded the Nobel Prize for Chemistry in 1903 [i, ii]. He has popularized the theory of electrolyte dissociation with his textbook on electrochemistry [iv]. Arrhenius worked in the laboratories of -> Boltzmann, L.E., -> Kohlrausch, F.W.G.,- Ostwald, F.W. [v]. See also -> Arrhenius equation. 

A large number of definitions for acids and bases have been introduced, but the 1923 definitions of J.N. Bronsted and T.M. Lowry are the most useful for discussions of ionic equilibria in aqueous systems. According to the Bronsted-Lowry model, an acid is a substance capable of donating a proton to another substance, such as water ... 

A new definition for acids and bases, building upon the one already proposed by Arrhenius, was brought forth independently by Johannes Nicolaus Bronsted and Thomas Martin Lowry in 1923. Tlie new definition did not depend on a substance s dissolution in water for definition, but instead suggested that a substance was acidic if it readily donated a proton (H ) to a reaction and a substance was basic if it accepted a proton in a reaction. 

Explain why the Arrhenius definitions for acid and base, and not the Bronsted-Lowry definitions, are used to describe whether an isolated substance is an acid or base.

One of the models which Lewis introduced in his book shall be the topic of this article which is written in the spirit that is expressed in the above-cited closing statement of the author. It is the general definition for acids and bases which now... 

We then learn the more general Bransted-Loivry definitions for acid and base. A Bronsted-Lowry acid is a proton donor and a Bronsted—Lowry base is a proton acceptor.
