基于新医科理念的"氧化还原反应和电极电位"实验改进
Experiment Improvement of "Redox Reaction and Electrode Potential" Based on the New Medical Concept
摘要
Abstract
The concept of "New Medical Science" represents a paradigm shift in medicine,extending its focus from a primarily treatment-oriented practices to a comprehensive lifecycle that includes prevention,treatment,and wellness.Guided by the principle of "New Medical Science",this paper conducts interdisciplinary innovation in the "Redox Reaction and Electrode Potential" experiment,a core component of the Basic Medical Chemistry Experiment curriculum.The innovation include:(1) Replacing concentrated ammonia with sodium ethylenediaminetetraacetate (Na4Y),a chelating agent commonly used in clinical settings,to alter the concentration of Cu2+/Zn2+in the experiment measuring battery electromotive force;(2) Substituting the Br2/Br-redox couple with the C6H6O6 (oxidized form)/C6H8O6 (reduced form) redox couple of vitamin C (Vc) to study the redox properties of different redox couples;(3) Introducing an experiment that involves the reduction of Fe3+by glutathione,fostering interdisciplinary thinking on the medically relevant process of cellular iron death.These modifications not only make the "Redox Reaction and Electrode Potential" experiment more eco-friendly but also bridge medical education and chemistry,underlining the importance of "New Medical Science" concept in foundational chemistry education.关键词
