Copper ions + CuIIClsub2AL

In summary, during the lab in chemistry, Copper Chloride Dihydrate was mixed with water and then an aluminum ball was added to the mixture. This caused the mixture to turn bluish green and eventually disintegrate. The teacher explained that this was due to the presence of copper ions. The "boiling" observed was actually the production of gas. The precipitate at the bottom of the mixture is likely a result of the reaction between the copper chloride and aluminum. Referring to the lab manual may provide additional information about the reaction.

We just did a lab in chemistry. My question is in regards to what chemically happened in the lab. this is what happened macroscopically:

procedures:
1.) Copper Chloride Dihydrate is put into water.
2.) One aluminum ball (regular Al that u can get in stores) is put inside this mixuture (1) after it is mixed.

Observations:
after 1 has been mixed, it becomes a bluish green color and continues to get darker.
after number 2, the Al sort of causes the mixture to boil and it slowly becomes disintegrated. There are tiny parts of it at the bottom of the mixture.

My teacher says that there were copper ions.

"boiling" are you sure this is not the production of gas?

What do you suppose that the precipitate is at the bottom of the mixture?

try referring to your lab manual for additional hints, I'm sure that there is enough information.

Based on the observations and procedures you have described, it seems that a single replacement reaction occurred between the aluminum and copper ions in the copper chloride dihydrate. When the aluminum was added to the solution, the aluminum atoms lost electrons and formed aluminum ions, while the copper ions gained electrons and formed solid copper atoms. This resulted in the observed color change and the disintegration of the aluminum ball. The reaction can be represented by the following equation:

Al(s) + CuIICl2(aq) → Al3+(aq) + 2Cl-(aq) + Cu(s)

This reaction is known as a redox reaction, where one element loses electrons (oxidation) and another element gains electrons (reduction). I hope this helps explain what chemically happened in the lab.
 

1. What is the formula for copper ions?

The formula for copper ions is Cu2+.
