已知的化学定性分析法大部分是以在水容液中进行反应作焉分析的基础。舆此相反,本书提出的新的定性分析法,是利用粉末研磨,靠固体物质之间所进行的反应作焉分析的基础。
Most of the known methods of chemical qualitative analysis are based on the analysis of reactions in water. On the contrary, the new qualitative analysis presented in this book is based on the analysis of the reactions carried out between solid materials using powder grinding.
