化学平衡是中学化学涉及的溶解平衡、电离平衡、水解平衡等知识的核心,既是高中化学基本理论部分的重要考点,也是化学教学中的一个难点,掌握分析平衡问题的思想方法是求解平衡问题的关键。在处理平衡问题的过程中常常要用 Chemical equilibrium is the core of knowledge of dissolution chemistry, ionization balance and hydrolysis balance in middle school chemistry. It is not only an important test point for the basic theory of chemistry in high school, but also a difficult point in chemistry teaching. To master the idea of ​​balancing is to solve the problem of balance The essential. It is often used in the process of balancing issues
