化学通报1957年7月号关于汪爵伯同志写的“我是怎样组织碱金属的复习课”一文,其中有很多优点,例如复习的多样化、教材前后的密切联系、注意到理论和实践的结合等。现就盐的水解及钠钾的制取钠钾氧化物等在碱金属一章中的位置问题,提出来供大家商榷。在全文中没有提到钠钾氧化物。关于钠钾的制取,只是在留给学生课后思考的问题中略微提到“电解食盐的稀溶液或熔融状态的食盐,结果怎样?为什么”?而对“盐的水解”不但在课堂上复习占到一定比例,并在教师总结时一再强调。从以上看来,汪同志对“盐的水解”在本章中的应有地位估价高了,而对钠
Chemical Symposium, July 1957 On Comrade Wang Jabo’s article, “How Am I Organizing an Alkali Metaphysical Review Course,” which has many advantages, such as the diversification of reviews, the close connection between textbooks, and the notion of theory and practice Combined and so on. Now on the hydrolysis of sodium and sodium and potassium sodium sodium potassium oxide system in the chapter on the location of the issue, put forward for your discussion. There is no mention of sodium potassium oxide throughout the text. About the preparation of sodium and potassium, it is only mentioned in the questions left to the students after class that “electrolysis salt dilute solution or molten salt, what is the result?” And “salt hydrolysis” not only in the classroom review Account for a certain percentage, and repeatedly stressed when the teacher concluded. From the above view, Comrade Wang appraised the proper position of “salt hydrolysis” in this chapter, while for sodium
