论文部分内容阅读
近两年来,高师院校分析化学课多采用华中师院等三校编的《分析化学》作为教材。它与过去的教材相比较,内容较新、范围较广,大部分内容易于讲授。讲好这部教材,下面仅就处理酸碱平衡方法中的质子条件问题谈一点自己的经验。 当讲到§7-3的“一、处理酸碱平衡的方法”中的质子条件问题时,觉得内容很新也较深,而教材中叙述得又过于概括,学生在阅读上有一定困难。几届学生(80、81级及函授生)反映:在写物料平衡、电荷平衡或质子条件时,抓不住要领,总是丢东拉西,不是多一项就是少一项,或将系数搞
In the past two years, most of the analytical chemistry classes in normal universities have adopted the “Analytical Chemistry” compiled by the three schools of Central China Normal University as teaching materials. Compared with the past teaching materials, it is newer in content, wider in scope, and much easier to teach. Speaking of this textbook, here only talk about your own experience on the proton conditions in the acid-base balance method. When it comes to the proton condition in §7-3, “I. A Method for Handling Acid-Base Equilibrium,” we find content is very new and deep. However, the teaching materials are overly summarized and the students have some difficulty in reading. Several students (grades 80 and 81 and correspondence students) reflect that when material balance, charge balance or proton conditions are written, they can not grasp the essentials and they always lose the Lacey, either one or the other less, or the coefficient Engage
