摘 要:高锰酸钾法测定补钙剂中钙的含量是一个经典的分析化学实验。本案例由“中国人普遍缺钙”这一调查结果作为切入点,引导学生利用所学理论知识测定市售某补钙剂产品中钙的含量,并开展分组实验重点探究草酸钙沉淀的生成条件及洗涤方法对补钙剂中钙含量测定结果的影响。将“思政寓课程,课程融思政”的教学理念贯穿于实验教学全过程中,能够提高学生学以致用的能力,切实培养他们的安全意识、环保意识、科学素养、团队意识及创新能力,同时强化其“每个人是自己健康第一责任人”的意识。The determination of calcium content in calcium supplement by potassium permanganate method is a classic experiment in analytical chemistry.This case is based on the investigation result of“widespread calcium deficiency among Chinese people”as a starting point,guiding students to use their theoretical knowledge to determine the calcium content in a commercially available calcium supplement product.Through group experiments,the focus is on exploring the influence of calcium oxalate precipitation conditions and washing methods on the determination of calcium content in calcium supplements.By integrating the teaching concept of“ideological and political education exists in the curriculum and integrates into the curriculum”throughout the entire experimental teaching process,Students’ability to apply what they have learned can be improved,and their awareness of safety and environmental protection,scientific literacy,team spirit and innovation ability can be effectively cultivated.At the same time,their awareness of“each individual is responsible for their own health”can be strengthened.
