Chemistry: Inorganic Qualitative Analysis in the Laboratory

Chemistry: Inorganic Qualitative Analysis in the Laboratory is a textbook dealing with qualitative analysis in the laboratory, as well as with the process of anion and cation analysis. The book presents an overview of the subject of inorganic qualitative analysis, including as the equipment, reagents, and procedures that are going to be used in the laboratory. Preliminary experiments include the classification of precipitates, handling precipitates, separation techniques, flame tests, Brown ring test, solvent extraction. The text also describes in detail how to prepare the experiment for anion and cation analysis such as testing for water solubility in a solid sample or the sodium carbonate treatment of a water-soluble sample. The book also explains the qualitative analysis for anions in preliminary and specific tests. In the qualitative analysis for cations, the student follows different procedures for Cation Groups I, II, III, IV or V. For example, the ions of Cation Group V cannot be precipitated by any Cation Groups I-IV reagents, nor by any single group reagent. The textbook is suitable for both chemistry teachers and freshmen students.
