复分解反应的概念和反应发生的条件出现在人教版义务教科书九年级下册第十一单元课题1。复分解反应的相关知识一直是初中教学中的重点、难点。正确理解教材编写者的意图,运用合适的方法理解、讲透复分解反应,对化学教学有重要的推进作用。按照教材的编写意图,首先让学生感性地认识酸和碱的性质。再从溶液的导电性上分析原因:酸、碱溶液 The concept of metathesis reaction and the conditions under which the reaction occurs appear in the tenth edition of the tenth volume of the ninth edition of the Volunteer Edition Voluntary Textbook. Metathesis reaction related knowledge has always been the focus of junior high school teaching, the difficulty. Correct understanding of the intent of the textbook writers, using the appropriate method to understand, through the decomposition reaction, the chemistry teaching has an important role in promoting. In accordance with the preparation of teaching materials intentions, first of all let the students perceive the nature of acids and alkalis. Again from the conductivity of the solution to analyze the reasons: acid, alkali solution
