酸碱盐一章是初中化学的最后一章，既是对前七章知识的总结，又是它们的延伸，且本章知识系统性较强，概念较多，涉及到的化合物种类及反应也多，反应规律也较复杂。因此，要学好酸碱盐知识，笔者认为要注意以下三个问题：一、要注意所学知识的应用学习酸碱盐一章的知识，不仅 The chapter on acid and alkali salts is the last chapter of junior high school chemistry. It is both a summary of the first seven chapters and an extension of them. This chapter is also more knowledgeable, more systematic, and involves more types of compounds and reactions. The law of reaction is also more complicated. Therefore, to learn the knowledge of acid-base salts, I believe that we should pay attention to the following three issues: First, we must pay attention to the knowledge of the application of knowledge to learn the chapter of acid-base salt, not only
