定性分析不仅在国民经济的许多部门具有很高的实际应用价值,而且作为一门化学系的专业课程又有很大的教育意义。它通过理论联系实际的教学,使学生既要学到常见离子及其化合物的性质、分离及鉴定的知识,又可以获得应用基本理论分析和解决问题的能力,还能提高实验操作的技能技巧。这些对于培养一名合格的中学化学教师说来,都是必须具备的。然而,由于教材中没有系统地讲授有关基本理论(用于定性分析的基本理论大
Qualitative analysis not only has high practical value in many departments of national economy, but also has great educational significance as a specialized course of chemistry department. By linking theory with practical teaching, students should not only acquire the knowledge of the nature, separation and identification of common ions and their compounds, but also acquire the ability to analyze and solve problems using basic theories and improve the skills and skills of experimental operations. These are all necessary to develop a qualified secondary school chemistry teacher. However, due to the lack of systematic teaching of basic theories (the basic theory for qualitative analysis
