The Arrhenius theory of acids and bases states that “an acid generates H + ions in a solution whereas a base produces an OH – ion in its solution”. The Bronsted-Lowry theory defines “an acid as a proton donor and a base as a proton acceptor”.

Arrhenius's Definition of Acids and Bases. The earliest definition of acids and bases is Arrhenius's definition which states that: An acid is a substance that forms hydrogen ions H + when dissolved in water, and; A base is a substance that forms hydroxide ions OH-when dissolved in water.

Acid-base reaction, a type of chemical process in which one or more hydrogen ions are exchanged between species that may be neutral (molecules, such as water or acetic acid), or electrically charged (ions, such as ammonium, carbonate, or hydroxide).

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.

Acid–base reactions require both an acid and a base. In Brønsted–Lowry terms, an acid is a substance that can donate a proton (H +), and a base is a substance that can accept a proton. All acid–base reactions contain two acid–base pairs: the reactants and the products.

Jan 30, 2023 · There are three major classifications of substances known as acids or bases. The Arrhenius definition states that an acid produces H + in solution and a base produces OH -. This theory was developed by Svante Arrhenius in 1883. Later, two more sophisticated and general theories were proposed.
