    Mar 2, 2026 · 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 …

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

    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

    Mar 2, 2026 · 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 …

  4. 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.

  5. 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, …

  6. 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 …

  7. Chemical reaction | Definition, Equations, Examples, & Types - Britannica

    Jan 13, 2026 · Classification by types of reactants include acid-base reactions and oxidation-reduction reactions, which involve the transfer of one or more electrons from a reducing agent to an oxidizing …

  8. Acid–base reaction - Alternative Definitions | Britannica

    Typical acid–base reactions may be thought of as the combination of two reaction schemes, A 1 ⇄ B 1 + H + and H + + B 2 ⇄ A 2, leading to the combined form A 1 + B 2 ⇄ B 1 + A 2. This represents a …

  9. 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 …

  10. 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 …
