摘要:
介绍了HA-A型标准缓冲溶液用最简式计算精确pH的两种思路。经证明,两种思路的最终结果一致,并用实例验证了思路二的正确性,有助于进一步培养学习者的推导能力和加深学习者对pH计算公式的理解,也是对现行分析化学教材有益的补充。
关键词: 标准缓冲溶液, 精确pH计算, 活度系数, 最简式
Abstract:
The two solutions of accurate pH calculation for HA-A standard buffer solution by the simplest form were introduced. Results from the two approaches agreed well with each other, and solution #2 was validated by examples. The calculation can improve the deduction ability of the learners and enhance their comprehensive understanding of pH computational formulas, and also be a useful supplement for current analytical chemistry textbooks.
Key words: Standard buffer solution, Accurate pH calculation, Activity coefficient, The simplest form
