Study Methodology of Analytical Group II Cations

The article analyzes properties, significance and application of metal cations of the II analytical group Ag^+ 〖, Pb〗^(2+),〖〖 [Hg〗_2]〗^(2+), formed on the basis of many years of experience in teaching chemistry. Principles with the following stages: base-acid classification of II analytical group cations: General characterization of cations of analytical group II with base-acid classification → Chemical bases of toxic action of their representative heavy metals - integration with ecology → Their importance and use in medicine - integration with medicine, solving the tasks of the teaching process of human life safety → Private reactions of identification - solving the tasks of the teaching process of chemistry → Control task: the course of analysis of II analytical group of cations in the course of systematic analysis → drawing up the results of private reactions and mixture analysis of II analytical group according to the given schemes → Laboratory work assessment system → Synthesis of information - multi-component analysis of the studied material.
