我们的化学世界里,平衡理论的应用无处不在,高中化学选修四课本中的化学平衡理论是高中学生在化学学习过程中感觉较困难的一部分,许多学生对这部分知识的印象是零散、多变,但对这部分内容的理解和掌握程度直接影响后续对电离平衡、盐类水解平衡等内容的学习,所以这部分内容在高中化学中起着重中之重的作用。本文针对化学平衡理论的应用及在应用中经常出现的一些问题作简单梳理,教学中有意识地将它们加以归纳和总结,可以使平衡理论知识系统化,便于学生对比学习。
In our chemistry world, the application of the theory of balance is ubiquitous. The chemical equilibrium theory in the four textbooks of high school chemistry electives is a part of high school students’ feeling of difficulty in chemistry learning. Many students are impressed by this part of knowledge However, understanding and mastery of this part of the content will directly affect subsequent learning on such topics as ionization balance and salt hydrolysis balance. Therefore, this part plays a very important role in high school chemistry. In this paper, the application of the theory of chemical equilibrium and some frequently-used problems in the application are briefly summarized, and they are summed up and summarized in the teaching consciously. The knowledge of the equilibrium theory can be systematized to facilitate students’ comparative study.
