　改进弱酸弱碱溶液pH值的计算

保持相对误差在5%以内.通过简化教科书pH值计算公式来计算弱酸弱碱溶液pH值.此方法拓宽了华东理工大学及成都科学技术大学分析化学教研组合编的《分析化学》教科书第4版弱酸弱碱溶液pH值的计算公式的实用范围

计算简便、实用.

The calculating methods of weak acid or weak base solution were studied. By simplifying the pH value formula in the textbook

the relative error is within 5%

and the pH value of weak acid or weak base solution is calculation. The method is more convenient and practical

and is widely-used than that in the teaching materials version IV.
