在学习《电解质溶液》一章时 ,学生对于电解质溶液中微粒浓度的比较 ,尤其是有等量关系的微粒浓度问题 ,常感到棘手 ,解答非常困难。对此 ,在教学中我尝试扩大知识面 ,补充引入三种等衡式的讲授 ,发现学生普遍能够接受 ,教学效果显著提高。三种等衡式其实是电解质溶液中三种平 When studying the “Electrolyte Solution” chapter, students often find it tricky to compare the concentration of particulates in electrolyte solutions, especially those with the same amount of particulate matter. In this regard, in my teaching, I tried to expand my knowledge and supplemented the introduction of three equal-balance teachings. I found that students were generally accepted and teaching effectiveness improved significantly. Three equal balances are actually three kinds of electrolyte solution
