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 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).
Learn the basics of acid-base chemistry. Get the definitions and examples of acids and bases and learn about the neutralization reaction.
An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.
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 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.
At the moment, we have two acid–base reactions: one in which water is the acid and the other in which water is the base. How can this be? How can one molecule of water be both an acid and a base, apparently at the same time?
An acid-base reaction is a chemical reaction that occurs between an acid and a base that are the reactants. The products of this reaction are salt and water. An acid-base reaction is a double-replacement reaction where ions exchange their positions.

The chemical opposite of an acid is a base. The equivalent definition of a base is that a base is a compound that increases the amount of hydroxide ion (OH −) in an aqueous solution.
