摘要：

两性物质的pH计算是无机化学中非常重要的内容。通过3个有代表性的例子(NaHCO3、 NH4CN、NaH2PO4),运用Matlab获得它们的pH、各物种的分布分数。可以帮助学生理解两性物质酸碱性原因,并让学生了解、学习Matlab在化学中的应用。

关键词: 两性物质, 分布分数, pH, Matlab

Abstract:

The pH calculation of amphiprotic species is a very important content in the inorganic chemistry course.In this paper, the calculation of pH and the distribution fraction as a function of pH using Matlab software are illustrated by three representative examples, NaHCO3, NH4CN, and NaH2PO4. This practice can help students further understand the fundamentals of the amphiprotic species, and enable students to understand and learn the application of Matlab software in chemistry.

Key words: Amphiprotic species, Distribution fraction, pH, Matlab
