医学院校基础化学实验“缓冲溶液的配制与性质”的改进与优化

Improvement and Optimization of Preparation and Feature of Buffer Solution in Basic Chemistry Experiment of Medical College

针对医学院校基础化学课程中关于缓冲溶液性质的实验存在的实验内容简单、检测方法单一等问题,提供了一系列的优化方法,如使用pH计测量、增设缓冲浓度梯度和缓冲比等。结果表明,学生不仅能掌握缓冲溶液的抗酸抗碱能力,还能更深地理解其缓冲作用原理。

Aiming at the problems of simple experiment content and single detection method in basic chemistry of medical college,We provide a series of optimization methods,such as using pH meter,adding buffer concentration gradient and buffer ratio.The results show that students can not only master the ability of acid resistance and alkali resistance of buffer solution,but also understanding the principle of buffer function more deeply.
