Buffer solution - Wikipedia
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.

2021年8月20日 · 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 .

2023年1月30日 · 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.

What Is a Buffer Solution? The buffer solution is a solution able to maintain its hydrogen ion concentration (pH) with only minor changes in the dilution or addition of a small amount of either acid or base.
Buffer Solution: Definition, Examples, and Preparation
What 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.
7.1: Acid-Base Buffers - Chemistry LibreTexts
2023年10月23日 · Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added (Figure \ (\PageIndex {1}\)). A solution of acetic acid (\ (\ce {CH3COOH}\) and sodium acetate \ (\ce {CH3COONa}\)) is an example of a buffer that consists of a weak acid and its salt.

2024年10月7日 · 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

A solution containing appreciable amounts of a weak conjugate acid-base pair is called a buffer solution, or a buffer. Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added ( Figure 14.14 ).
