  2. Brønsted–Lowry acid–base theory - Wikipedia

    en.wikipedia.org/wiki/Brønsted–Lowry_acid...

    The Brønsted–Lowry theory (also called proton theory of acids and bases [1]) is an acidbase reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923.

  3. Acid–base reaction - Wikipedia

    en.wikipedia.org/wiki/Acidbase_reaction

    In chemistry, an acidbase reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acidbase theories, for example, Brønsted–Lowry acidbase theory.

  4. Conjugate (acid-base theory) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_(acid-base_theory)

    One use of conjugate acids and bases lies in buffering systems, which include a buffer solution. In a buffer, a weak acid and its conjugate base (in the form of a salt), or a weak base and its conjugate acid, are used in order to limit the pH change during a titration process. Buffers have both organic and non-organic chemical applications.

  5. Johannes Nicolaus Brønsted - Wikipedia

    en.wikipedia.org/wiki/Johannes_Nicolaus_Brønsted

    In 1923, he recognized that acidbase reactions involved the transfer of a proton, from the acid (proton donor) to the base (proton acceptor). [8] Almost simultaneously and independently, the British chemist Martin Lowry arrived at the same conclusion, thus the name Brønsted–Lowry acidbase theory. [9]

  6. Amphoterism - Wikipedia

    en.wikipedia.org/wiki/Amphoterism

    According to the Brønsted-Lowry theory of acids and bases, acids are proton donors and bases are proton acceptors. [6] An amphiprotic molecule (or ion) can either donate or accept a proton, thus acting either as an acid or a base.

  7. Acid catalysis - Wikipedia

    en.wikipedia.org/wiki/Acid_catalysis

    In acid catalysis and base catalysis, a chemical reaction is catalyzed by an acid or a base. By Brønsted–Lowry acidbase theory, the acid is the proton (hydrogen ion, H +) donor and the base is the proton acceptor. Typical reactions catalyzed by proton transfer are esterifications and aldol reactions.

  8. Base (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Base_(chemistry)

    Bases and acids are seen as chemical opposites because the effect of an acid is to increase the hydronium (H 3 O +) concentration in water, whereas bases reduce this concentration. A reaction between aqueous solutions of an acid and a base is called neutralization , producing a solution of water and a salt in which the salt separates into its ...

  9. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    In water, measurable pK a values range from about −2 for a strong acid to about 12 for a very weak acid (or strong base). A buffer solution of a desired pH can be prepared as a mixture of a weak acid and its conjugate base. In practice, the mixture can be created by dissolving the acid in water, and adding the requisite amount of strong acid ...
