摘要： 对本科无机化学教学实验中“矿物药的鉴别”实验进行了改进，选用6种外观难以区分、类白色的矿物药粉末作为实验对象，创新地设计了矿物药鉴别的盲盒实验，并增加了含量测定内容，优化了部分离子的鉴别方法，能够让学生体会无机化学反应在药物鉴别和分析中的现实意义，并强化了本科生灵活运用理化反应原理解决实际问题的能力。

Abstract: This study introduces an enhanced approach to the undergraduate inorganic chemistry experiment, "Identification of Mineral Drugs", by selecting six mineral drug powders that are visually similar and predominantly white. Innovatively, a blind-box experiment for the identification for mineral drugs was designed, incorporating content determination to augment the experiment. Moreover, the identification methods for certain ions were optimized. This enhancement enables students to appreciate the practical significance of inorganic chemical reactions in the identification and analysis of drugs, significantly bolstering the ability of undergraduates to adeptly apply physical and chemical reaction principles in addressing practical challenges.
