1　实验改进目的形象地说明Ｃｕ2 +和Ｃ1-在外加电场的作用下 ,作定向移动。Ｃ1-向阳极移动 ,在阳极上失去电子 ,生成氯气 ,Ｃｕ2 +向阴极移动 ,在阴极上得到电子而析出铜。2　实验装置实验装置如图 1所示。图 1　电解氯化铜实验1,2 阴阳极碳棒 3 12 5ｍＬ烧杯 4 10 %ＣｕＳ 1 Experimental Improvement Objectives show vividly that Cu2 + and C1- are unidirectionally moved by the applied electric field. C1- moves to the anode, loses electrons on the anode, generates chlorine, Cu2 moves to the cathode, and electrons are collected on the cathode to deposit copper. 2 experimental device Experimental device shown in Figure 1.
