一、教材分析电离平衡是中学化学基础理论电解质溶液的一部分 ,是第二章化学平衡知识的拓展和深化 ,在高中化学教学中占有重要地位。本章教材共四节 ,可分为三部分。第一部分为第一节电离平衡 ,主要介绍强、弱电解质与结构的关系 ,弱电解质电离平衡的知识以及电离常数 ,这部分 First, the textbook analysis of ionization balance is a part of the electrolyte theory of the basic theory of chemistry in middle schools. It is the expansion and deepening of the knowledge of chemical equilibrium in the second chapter, which occupies an important position in the teaching of chemistry in high schools. There are four sections in this chapter, which can be divided into three parts. The first part is the first section of the ionization balance, which mainly introduces the relationship between strong and weak electrolytes and structures, the knowledge of the weak electrolyte ionization equilibrium, and the ionization constants.
