When copper chloride reacts with aluminum, the aluminum replaces the copper in the compound through a single displacement reaction. The resulting compound formed, aluminum chloride, is colorless in solution. Therefore, the color of the solution appears to fade as the copper is displaced and the products of the reaction are colorless.
Aluminum Chloride
Aluminum chloride is typically a white or colorless solid compound.
The formula for aluminum chloride is AlCl3.
When aluminum chloride is added to a ferric oxide solution, a chemical reaction occurs where the aluminum displaces the iron in the ferric oxide, forming aluminum oxide and iron chloride. This results in a color change and the formation of a precipitate of aluminum hydroxide.
Under IUPAC naming conventions, AlCl3 is called aluminum chloride. It is also commonly called aluminum trichloride and aluminum (III) chloride.
The correct name for AlCl3 is aluminum chloride. This is a compound made from chlorine and aluminum. It is usually a white or yellow salt-like inorganic compound.
The formula for aluminum chloride is AlCl3. This formula indicates that each molecule of aluminum chloride contains one aluminum atom and three chlorine atoms.
The reaction between copper chloride and aluminum forms aluminum chloride and copper metal. As the copper metal is formed, it precipitates out of the solution, causing the color of the copper chloride solution to fade. This happens because the copper ions are now in the solid copper metal form instead of the solution.
When copper chloride solution is mixed with aluminum, a redox reaction occurs where the aluminum reduces the copper ions to form copper metal. This results in a color change from blue-green (copper chloride solution) to colorless (copper metal precipitate), giving the appearance of fading in color due to the formation of a solid copper instead of a colored solution.
Aluminum III chloride is not a valid chemical formula.
When copper chloride and aluminum are combined, they react to form aluminum chloride and copper metal. This is a displacement reaction where aluminum replaces copper in the chloride compound.
