东北高中化学第一章“盐及其制法”有些同志认为系统性比较差且不甚完整。为了说明盐的有系统的生成法以便理解和记忆特将‘化学通报’第一期俞崇智同志所列的第三表修改如下,并附实例以供教学的参考,是否有当,尚祈诸同志提正。 Northeast High School Chemistry Chapter “Salt and its preparation” Some comrades think that the system is relatively poor and not complete. In order to illustrate the systematic production of salt for understanding and memory, the third table set forth by Comrade Yu Chongzhi in the first issue of Chemical Bulletin, is amended as follows, with examples for educational reference. Comrades correct.
