高中学生要学好化学,必须对这些繁杂、多样、零碎的知识点进行有效的对比、归纳、整理,在重视知识相似性的同时更应该重视一些知识点的差异性,巧妙地利用这些差异化的知识,可以解决许多化学问题。本文试从高中化学教材中有关知识的差异性入手,深入挖掘应用这些差异化知识解决一些具体化学问题时存在的误区,使师生在教学过程中以资借鉴。

For high school students to learn chemistry, these complex, diverse, and fragmented knowledge points must be effectively compared, summarized, and sorted out. While emphasizing knowledge similarity, attention should also be paid to differences in some knowledge points, and skillful use of these differentiated Knowledge can solve many chemical problems. This article tries to start with the differences in the knowledge of high school chemistry textbooks, and digs deeper into the misunderstandings of applying these differential knowledge to solve some specific chemical problems, so that teachers and students can learn from the teaching process.
