课本上铝与硫酸铜反应生成“铜树”实验的实质是置换反应。某化学小组用家中自制的简陋装置完成这个实验,并得到了一些启示。实验装置取一铝制易拉罐,剪去两底,取其铝片。擦去其表面的氧化物,之后将铝片剪成树状,并塞人事先洗净的雪碧塑料瓶中。取胆矾25克～30克加入雪碧瓶,之后注水,以没过树状铝片为宜,再拧 The essence of the reaction between aluminum and copper sulphate to produce the “copper tree” experiment is the displacement reaction. A chemical team used the home-made simple device to complete this experiment and gained some inspiration. The experimental device takes an aluminum can, cuts the two bottoms, takes the aluminum piece. Wipe the oxides on the surface, then cut the aluminum pieces into a tree shape and plug them into the previously washed Sprite plastic bottle. Take a bottle of 25 grams to 30 grams of shampoo and add it to a bottle of Sprite, then fill it with water.
