Lewis (1875–1946) refined the acid and base concept to include dissolution events in nonaqueous solvents, where free protons are not involved. Developing along with these theoretical considerations, the prac-tical measurement of acidity has a long history, and this practice is at the founda-tion of analytical chemistry and ultimate-
In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
Nov 13, 2022 · Arrhenius Definition. "an acidic substance is one whose molecular unit contains at least one hydrogen atom that can dissociate, or ionize, when dissolved in water, producing a hydrated hydrogen ion and an anion." hydrochloric acid. HCl → H +(aq) + Cl –(aq) sulfuric acid. H 2 SO 4 → H +(aq) + HSO 4–(aq)
acid–base reaction, a type of chemical process typified by the exchange of one or more hydrogen ions, H +, between species that may be neutral ( molecules, such as water, H 2 O; or acetic acid, CH 3 CO 2 H) or electrically charged (ions, such as ammonium, NH 4+; hydroxide, OH −; or carbonate, CO 32− ). It also includes analogous behaviour ...

The Arrhenius definition of acid-base reactions is a development of the "hydrogen theory of acids". It was used to provide a modern definition of acids and bases, and followed from Arrhenius's work with Friedrich Wilhelm Ostwald in establishing the presence of ions in aqueous solution in 1884.
