在人教版九年级化学(下册)以及高中必修化学1教材中,都出现了一个大家非常熟悉的实验,那就是铝与硫酸铜溶液的反应从所提供的图片可以看出,在该反应中铝将铜单质从其化合物中置换出来形成了漂亮的铜树,非常形象而直观。但在现实操作中根据教材所提供的方法却很难达到图片中所看到的效果,该反应速率非常缓慢且难以形成较为立体宏观的铜树。对此,笔者经过探索对该实验做了一些改进
In the PEP 9th grade chemistry (second volume) and the high school compulsory chemistry 1 textbooks, there has been a very familiar experiment, that is aluminum and copper sulfate solution reaction can be seen from the provided picture, in the reaction Chinalco replaces the simple substance of copper from its compound to form a beautiful copper tree, which is very vivid and intuitive. However, according to the teaching methods provided in the actual operation, it is very difficult to achieve the effect as seen in the picture. The reaction rate is very slow and it is difficult to form a more three-dimensional macroscopic copper tree. In this regard, I made some improvements to the experiment after exploration
