在高中化学必修一中,离子反应作为一个非常重要的反应类型,要求学生能够判断离子反应和非离子反应,能够写出离子方程式,能够理解离子反应的意义和重要应用等。该内容的出现是在刚刚学习了物质分类后的一次重要的应用,化学反应根据分类标准不同,分为不同的类型,有根据反应物或者生成物的类别和种类分的;是否有电子的转移分的;是否有离子参与反应分的;还有反应进行的程度分的等很多种分法。同时也是初中学习溶液导电性实验、酸碱盐电离知识的延续和深化,又是学习电解质溶液理论知识的基础,起承上启下的作
In high school chemistry compulsory one, ion reaction as a very important reaction type, require students to judge ion reaction and non-ionic reaction, can write ion equation, can understand the significance of ion reaction and important applications. The content appears just after studying the material classification of an important application, chemical reactions according to the different classification criteria, divided into different types, according to the reactants or products of the types and types of points; whether there is electronic transfer Points; whether there are ions involved in the reaction points; there is a degree of reaction points and many other points. At the same time, it is also a continuation and deepening of the conductivity experiment of junior high learning solution and the knowledge of acid-base salt ionization. It is also the basis for studying the theoretical knowledge of electrolyte solution.
