初中化学课本第六章氧化物、酸、碱和盐,这一章是在前几章的基础上,对物质系统研究的开始。课本对各类物质作了较系统的介紹,这为学生今后的继续学习打下了基础。在这一章的教学中主要关键是注意知识的系统性,除此以外,根据我校的教学经验,在这一章的教学中还应注意以下几点: 第一点是对盐的性质的教学,課本中对盐的性质只在物理性质方面作了簡单的介紹,说明所有的盐都是固体,通常是規则的晶体,許多种盐具有颜色,各种盐的溶解度各不相同。課本中根本沒提到盐的化学性质,根据需要我认为有补充盐的化学性质的必要。系統讲解盐的化学性质时,一方面对酸和碱的部分化学性质作了复习,同时也将盐的知识充实系统了,更重要 Junior high school chemistry textbook Chapter VI oxides, acids, alkalis and salts, this chapter is based on the previous chapters, the beginning of the study of the material system. Textbook made a more systematic introduction to all kinds of material, which lays the foundation for the students to continue studying in the future. In this chapter, the main key is to pay attention to the systematic knowledge of knowledge, in addition, based on our teaching experience, the teaching of this chapter should also pay attention to the following points: The first point is the nature of the salt Teaching, the nature of the salt in the textbook is only a brief introduction to the physical properties, indicating that all the salt is solid, usually regular crystals, many kinds of salt with color, the solubility of various salts vary. There is no mention of the chemical nature of the salt in the textbook, and I think it necessary to supplement the chemical nature of the salt, as needed. While systematically explaining the chemical properties of salts, we have reviewed some of the chemical properties of acids and alkalis and enriched the system of salt knowledge
