HA-A型标准缓冲溶液用最简式计算精确pH的两种思路

Two Solutions of Accurate pH Calculation for HA-A Standard Buffer Solution by the Simplest Form

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。

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.
