摘　　要：对双氧水与铜的反应进行了实验研究,分析了酸性和外加氨水的条件下双氧水氧化单质铜的原因。解析了一道关于利用废旧电路板中铜制备胆矾的工艺流程高考题,提出了关于配位平衡移动问题的教学策略与建议。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.
