Improvement in the Experimental Teaching Design of Physical and Chemical Identification and Quantification of Mineral Drugs

National Experimental Teaching Demonstration Center for Traditional Chinese Medicine, School of Pharmacy, Nanjing University of Traditional Chinese Medicine, Nanjing 210023, China

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.
