Testing the Buffer Capacity of Baby Wipes: An Experiment Close to Life
Abstract:
In order to effectively enhance students' interest and enthusiasm in learning buffer solution, a case of introducing real daily necessities into laboratory teaching is recommended. The experimental design extends the property test to the baby wipe, and changes the content of the experiment into the verification of the working principle of wipe, instead of preparation of simple acid-base system and related verification experiments in the past. Through the implementation of this experiment, students generally reflected that it can effectively stimulate their enthusiasm and interest in learning buffer solution related contents, and ultimately promote them to recognize the characteristics and buffer mechanism of pH changes in buffer system.
