对各种分析方法所根据的反应进行精密的物理化学研究,是现代分析化学的基础。然而,关於分析反应的性质,机构以及所生成的化合物在固态及在溶液中的状态的最详尽的资料,是在把Н.С库尔纳科夫及其共同工作者所研究的物理化学分析法应用到金属、盐类、有机和其他体系的研究时得到的。物理化学分析的主要原理,就是测定某一体系的依赖於其组成的某些性质。测定的结果以组成-性质图来表示。在图上可以反映出化学作用的各个方面,而这些化学作用的很多方面是在采用其他研究方法时往往观察不到 The precise physicochemical studies of the reactions under which various analytical methods are based are the foundations of modern analytical chemistry. However, the most exhaustive information on the nature of the reaction, the organization and the states of the compounds produced in the solid state and in solution is obtained by combining the physico-chemical analyzes studied by Н.С Kurornkov and co-workers Law applied to the study of metals, salts, organic and other systems obtained. The main principle of physicochemical analysis is the determination of certain properties of a system that depend on its composition. The result of the measurement is shown as a composition-property graph. Various aspects of chemistry can be reflected in the graph, and many aspects of these chemistries are often not observed with other research methods
