  1. Acid-base reaction | Definition, Examples, Formulas, & Facts | Britannica

    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 …

  2. Acid–base reaction - Theories, Definitions, Properties | Britannica

    Nov 21, 2025 · Acid–base reaction - Theories, Definitions, Properties: The first attempt at a theoretical interpretation of acid behaviour was made by Antoine-Laurent Lavoisier at the end of the 18th century.

  3. Acid–base reaction - Equilibria, Neutralization, pH | Britannica

    Acid–base reaction - Equilibria, Neutralization, pH: Certain general principles apply to any solvent with both acidic and basic properties—for example, water, alcohols, ammonia, amines, and acetic acid.

  4. Acid–base reaction - Catalysis, Equilibrium, Reactions | Britannica

    Nov 21, 2025 · Acid–base reaction - Catalysis, Equilibrium, Reactions: Acids (including Lewis acids) and bases act as powerful catalysts for a great variety of chemical reactions, in the laboratory, in industry, …

  5. Chemical compound - Acid, Base, Reactions | Britannica

    Feb 10, 2026 · In acid-base reactions a proton is transferred from an acid to a base. If the acid and base are neutral molecules, the product is a positive ion and a negative ion and is known as a salt.

  6. Acid–base reaction - Aqueous Solutions, pH, Buffers | Britannica

    Acid–base reaction - Aqueous Solutions, pH, Buffers: Since aqueous solutions are of particular importance in the laboratory and in the physiology of animals and plants, it is appropriate to consider …

  7. Acid–base reaction - Bronsted-Lowry, Definition, Chemistry | Britannica

    Nov 21, 2025 · It can be summarized by the equation A ⇄ B + H +, in which A and B together are a conjugate acid–base pair. In such a pair A must obviously have one more positive charge (or one …

  8. Chemical reaction - Bronsted-Lowry, Acids, Bases | Britannica

    Jan 13, 2026 · Dissolving an acid in water to form the hydronium ion and the anion of the acid is an acid-base reaction. Acids are classified as strong or weak, depending on whether the equilibrium favors …

  9. What happens during an acid–base reaction? | Britannica

    An acid–base reaction is a type of chemical reaction that involves the exchange of one or more hydrogen ions, H +, between species that may be neutral (molecules, such as water, H 2 O) or …

  10. Acid–base reaction - Nonaqueous Solvents | Britannica

    Since many acid–base reactions involve an increase or decrease in the number of ions, they are also influenced by the dielectric constant of the solvent, for a higher dielectric constant favours the …
