Abstract This paper introduced an interactive personal response system based on the flipped classroom, and used a kind of new raw material-battery level foam copper with large specific surface area to carry out the reaction between nitric acid and copper under full protection. Then analyzed the products of the reactions of concentrated nitric acid and dilute nitric acid with copper respectively, and inquired the green solution left by the reaction of concentrated nitric acid with copper. The whole process was safe with obvious phenomena, and students could participate actively.
