WEBAug 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 .
Introduction to Buffers - Chemistry LibreTexts
WEBJan 30, 2023 · A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.
Buffer solution - Wikipedia
WEBA 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. Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications.
Buffer Solution: Definition, Examples, and Preparation
WEBWhat is a Buffer Solution [1-3,5-6] An aqueous solution that resists any change in pH by adding a small amount of acid or base is called a buffer solution. A buffer solution consists of a weak acid and its conjugate base or a weak base and its conjugate acid.
Properties of buffers (video) | Buffers | Khan Academy
WEBA buffer solution is an equilibrium between a weak acid and its conjugate base essentially. What’s happened is that a portion of the conjugate base has neutralized added acid to form new weak acid. These simultaneous changes make sure equilibrium is maintained.

WEBbuffer, 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 (CH 3 COOH) and sodium acetate.
