摘　　要：本实验运用电化学的方法,将简单易得的材料用于快速制备铜锈,在几十秒到几分钟不等的时间就会迅速产生铜锈。依据XRD图谱对产物进行分析,确定了形成碱式氯化铜(Cu_(2)Cl-(OH)_(3))的最佳电解质溶液配比,并成功制备了碱式碳酸铜(Cu_(2)(CO_(3))(OH)_(2))。实验结果可用作中学化学教学演示实验和学生实验,也可用于指导学生探究不同条件对铜锈制备的影响,进行探索性学习练习。此外,相关实验原理可提供试题情境对学生学习质量进行评价。In this experiment,simply and easily available materials were used to rapidly prepare copper rust by electrochemical method.Copper rust would be produced rapidly in a time ranging from dozens of seconds to a few minutes.The product was analyzed by XRD pattern,and the optimum electrolyte solution ratio for the formation of basic copper chloride(Cu_(2)(OH)_(3)Cl)was determined,and the basic copper carbonate(Cu_(2)(CO_(3))(OH)_(2))was successfully prepared.The experimental results can be used for middle school chemistry teaching demonstration experiment and student experiment,and can also be used to guide students to explore the influence of different conditions on copper rust preparation and carry out exploratory learning exercises.In addition,relevant experimental principles can provide test context to evaluate students’learning quality.
