6.1: What is an Acid and a Base? - Chemistry LibreTexts
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.
Acids and Bases - Definition, Examples, Properties, Uses with ...
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.
Acid-base reaction | Definition, Examples, Formulas, & Facts ...
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).

Acids and Bases Terms and Definitions - ThoughtCo
2019年5月5日 · There are several methods of defining acids and bases. While these definitions don't contradict each other, they do vary in how inclusive they are. The most common definitions of acids and bases are Arrhenius acids and bases, Brønsted-Lowry acids and bases, and Lewis acids and bases.
4.7: Acid Base Reactions - Chemistry LibreTexts
2022年7月4日 · 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.
Definitions of Acids and Bases, and the Role of Water
These definitions tie the theory of acids and bases to a simple laboratory test for acids and bases. To decide whether a compound is an acid or a base we dissolve it in water and test the solution to see whether the H + or OH-ion concentration has increased.
