化学平衡知识是学习电离平衡、盐类的水解以及溶液的PH值等知识的基础,也是在化工生产过程中选择适宜条件时必须掌握的基本理论。因此要引导学生理解化学平衡的概念,掌握化学平衡移动的规律,更好地为化工生产提供了理论依据。 Knowledge of chemical equilibrium is the basis for learning the ionization balance, salt hydrolysis and PH value of the solution, but also the basic theory that must be mastered in the selection of appropriate conditions in the chemical production process. Therefore, we should guide students to understand the concept of chemical equilibrium, grasp the law of chemical equilibrium shift, and provide a theoretical basis for chemical production.
