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.
