  2. 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.

  3. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    A Lewis base is often a Brønsted–Lowry base as it can donate a pair of electrons to H +; [11] the proton is a Lewis acid as it can accept a pair of electrons. The conjugate base of a Brønsted–Lowry acid is also a Lewis base as loss of H + from the acid leaves those electrons which were used for the A—H bond as a lone pair on the ...

  4. 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.

  5. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    For alkaline buffers, a strong base such as sodium hydroxide may be added. Alternatively, a buffer mixture can be made from a mixture of an acid and its conjugate base. For example, an acetate buffer can be made from a mixture of acetic acid and sodium acetate. Similarly, an alkaline buffer can be made from a mixture of the base and its ...

  6. Conjugation - Wikipedia

    en.wikipedia.org/wiki/Conjugation

    Conjugate vaccine, in immunology; Conjugation (biochemistry), covalently linking a biomolecule with another molecule; Conjugate (acid-base theory), a system describing a conjugate acid-base pair; Conjugated system, a system of atoms covalently bonded with alternating single and multiple bonds

  7. Brønsted–Lowry acid–base theory - Wikipedia

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

    The acid, HA, is a proton donor which can lose a proton to become its conjugate base, A −. The base, B, is a proton acceptor which can become its conjugate acid, HB +. Most acidbase reactions are fast, so the substances in the reaction are usually in dynamic equilibrium with each other. [8]

  8. Lewis conjugate - Wikipedia

    en.wikipedia.org/wiki/Lewis_conjugate

    In chemistry, a Lewis conjugate may refer to: The conjugate acid of a Lewis base or the conjugate base of a Lewis acid A molecule having a conjugated system of bonds in its Lewis structure

  9. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    For aqueous solutions of an acid HA, the base is water; the conjugate base is A − and the conjugate acid is the hydronium ion. The Brønsted–Lowry definition applies to other solvents, such as dimethyl sulfoxide : the solvent S acts as a base, accepting a proton and forming the conjugate acid SH + .
