The tutorial covers general issues of qualitative chemical analysis, the basis for the classification of cations and anions. The most important analytical properties and reactions of detection of cations of I-V analytical groups by sulfide classification are described. Analysis schemes and recommendations for systematic and fractional analysis of cations and anions are given. General approaches and recommendations for the analysis of a substance of unknown composition and the basis for a qualitative analysis of organic compounds are considered. The textbook is intended for students of chemical areas of preparation of all forms of training studying the course of analytical chemistry.
