Abstract This paper studied the reaction of hydrogen peroxide with copper by experiments, and analyzed the reason that hydrogen peroxide oxidized copper under the condition of adding acid and ammonia. Then this paper analyzed a college entrance examination question on the technological process of preparing copper sulfate from copper in waste printed circuit boards, and put forward some teaching strategies and suggestions on the problem of coordination equilibrium movement.
