Copper II Sulfate Aluminum Reaction

Taking the reaction between copper sulfate and aluminum as an important story
In the past, some craftsmen wanted to explain the reaction between copper sulfate (Copper II Sulfate) and aluminum (Aluminum), so they took a purifier and filled it with an appropriate amount of copper sulfate liquid. Its color is dark blue, clear and reflecting light. Take the aluminum sheet again, wipe it with dust, and make it clean. Then place the aluminum sheet lightly in the copper sulfate liquid.

Russia, see the junction between the liquid and the aluminum, there is a strange phenomenon. On the aluminum sheet, there is gradually a red matter, if Zhu Hua first blooms, it is attached to the aluminum table. In this red case, copper is also more active than copper. According to chemical reasons, aluminum can replace the position of copper in copper sulfate, so copper precipitates. The corresponding formula is: $2Al + 3CuSO_ {4} = Al_ {2} (SO_ {4}) _ {3} + 3Cu $.

At the same time, looking at the liquid, the blue is gradually fading. The reason why copper sulfate is blue is due to copper ions. As copper precipitates, copper ions gradually decrease, and the blue of the liquid is light. And the wall of the detector has a slight feeling of warmth, which should be the response of exothermic heat. Although the heat is not very strong, it can be felt.

After a while, the surface of the aluminum sheet becomes more and more red, as if it were covered with red clothes. The aluminum sheet also gradually erodes, and its shape changes slightly. This is also a sign of the phase of copper sulfate and aluminum. The craftsman recorded its image in detail, studied its principles carefully, and added new knowledge to the way of chemistry. Although this is a small response, it is of great benefit to the change of things and the exploration of principles.
