1CO还原氧化铜的实验改进(1实验装置(如图1图1(2)原实验的缺点①实验装置复杂,操作繁琐;②实验现象不明显,成功率很低;③容易造成CO泄漏,影响教师、学生的健康。(3)实验操作①往锥形瓶中加入少量澄清石灰水;②把直径2mm铜线弹簧放在酒精灯上灼烧成黑色氧化铜表层;③往锥形瓶内 1CO reduction of copper oxide experimental improvements (1 experimental device (Figure 1 Figure 1 (2) the original experimental shortcomings ① experimental device complex, cumbersome operation; ② experimental phenomenon is not obvious, the success rate is very low; ③ likely to cause CO leakage, the impact Teachers and students health. (3) Experimental operation ① Add a small amount of clarified lime water to the conical flask; ② The copper wire spring diameter 2mm on the alcohol lamp burning into a black copper oxide surface; ③ into the conical flask
