| 설명 | 혈압, pH 등과 같이 생체의 기능 및 상태를 안정시키고자 하는 작용 : pH 7인 순수한 물에서 소량의 산 또는 알칼리를 가하면 그 양에 따라 물의 pH가 뚜렷하게 변한다. 그러나 약한 산과 그 염의 혼합용액, 또는 약한 산기와 그 염의 혼합용액으로 이루어지는 계에서는 약간의 산 또는 알칼리를 가해도 완충작용 때문에 pH는 거의 변하지 않는다. 예를 들어, 약한 산과 그 염의 혼합용액으로 이루어지는 계系에 산을 가했을 때를 생각하면, 산에 의해서 가해진 수소이온 H+은 약한 산이온과 결합하여 비해리인 산이 되어 pH가 변하지 않는다. 또 알칼리를 가했을 때는 가해진 수산이온 OH－이 H+과 결합하여 물을 만들고, 부족한 H+은 비해리 약한 산의 해리에 의해서 보충되므로써 역시 pH는 변하지 않는다. |

| buffer index | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
| buffer pair | An acid and its conjugate base (anion). (05 Mar 2000) |
| buffer value | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
