盐类的水解,排在电离学说这一章的最后,这样当学生掌握了原子結构学说和电离学说的基本概念以后来进行盐类水解的教学,这就不但有了条件和可能,同时亦有了必要,通过盐类水解的教学,不但进一步加深和巩固了原子結构和电离学說有关的基本概念和为碳族元素的教学打下基础,同时从理論上解释了农业生产中所遇到的实际问题,直接的起到了为生产服务的目的,故教材这样的安排是恰当的,而且是重要的。
The hydrolysis of salts is at the very end of the chapter on ionization, so that when students master the basic concepts of atomic structure and ionization, teaching salt hydrolysis, there are not only conditions and possibilities, but also It is necessary that the teaching of salt hydrolysis not only further deepens and consolidates the basic concepts related to atom structure and ionization theory and lays the foundation for the teaching of carbon group elements but also theoretically explains the actual problems encountered in agricultural production The problem has directly served the purpose of production and service. Therefore, arrangements like teaching materials are appropriate and important.
