H2 reduction CuO experiment is a demonstration experiment and student experiment in junior high school chemistry textbook (shown in Fig. 1). Although the experiment is simple and the phenomenon is obvious, considering the safety principle and the green principle of chemical experiment design, the There are two drawbacks to the experiment. One is whether or not hydrogen is discharged before heating
