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,
