关于溶解度的计算,这是初中化学中一个重要问题,同时,又是运用所学化学知识和培养学生解决实际问题能力的关键的一课。如果这一课上不好,将会挫伤同学们的学习积极性,更会严重影响今后化学计算的教学。对此,我们认为,首先应当使学生对溶液、溶解平衡、饱和溶液和溶解度等基本概念有一个清晰明确的认识,弄清它们之间的 Regarding the calculation of solubility, this is an important issue in junior high school chemistry. At the same time, it is a key lesson in using the knowledge of chemistry and developing students’ ability to solve practical problems. If this class is not good, it will dampen the students’ enthusiasm for learning, and it will seriously affect the teaching of future chemical calculations. In this regard, we believe that students should first have a clear and clear understanding of the basic concepts of solution, dissolution equilibrium, saturated solution, and solubility, etc.
