介绍了溶液中弱电解质平衡体系的pH计算是《无机化学》课程中的重要基础理论知识。为简化计算经常需要引入近似条件，这样必然造成误差。通过理论计算解释了不同c／ka^o值与解离度误差的关系和不同解离度误差对应的c／ka^o值，对学生正确理解相关内容大有助益，是教材内容的必要补充。

Inorganic Chemistry is a very difficult course for college students to understand because of its special way of thinking. It is an important knowledge to calculate pH in dissociated system of weak electrolyte. Approximate factors are often adopted in order to simplify calculation and that must cause some errors. It is discussed in the paper about the relationship between the ratio of c/ka^o and error of dissociation degree,different errors corresponding to different c/ka^o. They are extra supplements to textbooks and it is helpful for the students to understand better.
