A solution whose pH is not altered to any great extent by the addition of small quantities of either an acid or base is called buffer solution. Buffer is also defined as the solution of reserve acidity or alkalinity which resists change of pH upon the addition of a small amount of acid or alkali.

A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it.
A buffer solution consists of a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer solution can resist pH change because of an equilibrium between the acid (HA) and its conjugate base (A –). The balanced equation for this reaction is: HA ⇋ H + + A –.
Aug 20, 2021 · A buffer (or buffered) solution is one that resists a change in its pH when H + or OH – ions are added or removed owing to some other reaction taking place in the same solution. Buffers do so by being composed of certain pairs of solutes: either a weak acid plus its conjugate base or a weak base plus its conjugate acid .
Aug 31, 2024 · Buffer, in chemistry, solution usually containing an acid and a base, or a salt, that tends to maintain a constant hydrogen ion concentration. Ions are atoms or molecules that have lost or gained one or more electrons. An example of a common buffer is a solution of acetic acid (CH3COOH) and sodium.
