Taking the experiment of the "identification of Co2+" as an example, this article elaborates the flexible application of "flipped classroom" model in the chemical laboratory teaching. Specifically, students do the experiment first and have questions during the experimental process, then the teacher discusses and demonstrates with students base on their questions, leading students to reunderstand the classic experiment of the "identification of Co2+". Thus this article reveals about how to educate students to think and criticize in the teaching process.

Key words: Chemical laboratory teaching, Identification of Co2+, Reunderstanding, Flipped Classroom, Criticizing
