Also question is, what happens when aluminum foil reacts with copper chloride?
Therefore when aluminum foil is put into the copper salt solution, aluminum atoms on the surface of the foil (in contact with the solution) reacts and takes the place of copper(II) ions in the solution (it now becomes aluminum chloride solution). That is why the blue solution becomes colorless.
Secondly, why does aluminum dissolve in copper chloride? Aluminum metal is always covered in a thin, but protective layer of aluminum oxide, Al2O3. The chloride ion helps to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
Also, does aluminum react with copper chloride?
What is the chemical reaction of copper(II) chloride mixed with aluminum? Copper (II) ions will hydrolyze to produce an excess of hydrogen ions, making the copper (II) chloride solution slightly acidic. Aluminum metal is always covered in a thin, but protective layer of aluminum oxide, Al2O3.
What does copper chloride react with?
CuCl2 reacts with several metals to produce copper metal or copper(I) chloride with oxidation of the other metal. To convert copper(II) chloride to copper(I) derivatives, it can be convenient to reduce an aqueous solution with sulfur dioxide as the reductant: 2 CuCl2 + SO2 + 2 H2O → 2 CuCl + 2 HCl + H2SO.
