《酸碱盐》是初中化学的最后一章,是对初中化学知识的归纳总结.本章在前几章知识的基础上,进一步将常见的无机化合物按酸、碱、盐、氧化物加以分类,使得我们对几类重要的无机化合物形成比较完整的认识,并学习从一般到特殊的认识事物的规律.为了对本章知识有比较系统的认识,可以从以下几个方面着手. “Acid-base salt” is the last chapter of junior middle school chemistry. It summarizes the knowledge of junior high school chemistry. Based on the first few chapters, this chapter further classifies common inorganic compounds as acids, alkalis, salts, and oxides. This allows us to form a relatively complete understanding of several important types of inorganic compounds, and to learn from the general to the special understanding of the laws of things. In order to have a more systematic understanding of this chapter of knowledge, you can start from the following aspects.
