补充资料：缓冲溶液
| 缓冲溶液 buffer solution 能抵抗外加的少量酸或碱或溶液的稀释，使其本身pH值不发生显著变化的溶液 。它们可以是弱酸及其盐 （如乙酸-乙酸钠；碳酸-碳酸氢钠 ）、多元弱酸的酸式盐及其次级盐（如磷酸二氢钠-磷酸氢二钠；碳酸氢钠-碳酸钠）、弱碱及其盐（氨水 - 氯化铵）组成的溶液。以乙酸-乙酸钠（HAc-NaAc）溶液为例，可说明缓冲溶液的缓冲作用 。在该溶液中存在下列电离过程： HAc  H+＋Ac-NaAc  Na+＋Aс-NaAc在水溶液中完全电离，由于同离子效应，降低了HAc的电离度，使HAc和Ac-的浓度都较大。在HAc-NaAc溶液中加入少量强酸，H+便和溶液中的Ac-结合生成HAc，使电离平衡向左移动，在达到新的平衡时，H的浓度不会显著增加。NaAc是缓冲溶液的抗酸成分。如果在HAc-NaAc溶液中加入少量强碱，增加的OH-与溶液中的H+结合生成水，电离平衡向右移动，以补充H+的减少，建立新平衡后，溶液中的H浓度也几乎保持不变。HAc是缓冲溶液的抗碱成分。在工农业生产和科学实验以及人体生理活动中常常要使溶液的pH值在某些条件变化时仍保持在一定的范围内，就需要有缓冲溶液的参与。例如在人体血液中存在着碳酸和碳酸氢盐，它们组成的缓冲溶液能够严格控制血液的酸碱平衡，使血液的pH值保持在7.4左右。当血液的pH值大于7.8或小于7.0时会导致死亡。 |
