在学习了金属的化学性质后,我们知道,铝的活动性比铜强,所以铝可以把硫酸铜溶液中的铜置换出来。在教材的图片中我们可以看到,把铝丝放进硫酸铜溶液中,铝丝表面析出了厚厚的一层红色铜粉,溶液也由蓝色变成无色。为了进一步了解铝和硫酸铜溶液的反应,我进行了一次有趣的探究。 After learning the chemistry of metals, we know that aluminum is more active than copper, so that aluminum can displace the copper in the copper sulfate solution. In the pictures of the teaching materials we can see that the aluminum wire into the cupric sulfate solution, aluminum surface precipitated a thick layer of red copper powder, the solution also changed from blue to colorless. In order to understand more about the reaction of aluminum and copper sulfate solution, I conducted an interesting exploration.
