Copper, Aluminum Chloride, and Heat.

2Al (s) + 3CuCl2 (aq) --> 3Cu (s) + 2AlCl3 (aq)
The aluminum metal appears to be turning into copper, but it is actually just removing the metallic copper from its compound state. The Aluminum is oxidized and loses e-, becoming Al 3+ and the copper ions are reduced (they accept those e-) to form solid copper precipitate. The aluminum ions and chloride ions remain in the solution. The reaction will only occur in water and occurs because the transfer of electrons from the aluminum to the copper results in a more stable system.
The two are highly reactive when mixed in water. If you add aluminum to a water solution of copper chloride, the aluminum will be combined as aluminum chloride gas, releasing the copper into the water. The mixture will turn very hot, bubble up, and start to smoke, and the color will change from blue to dark red. ========================= The first sentence is correct, the two are highly reactive, but from there on, there are problems... There's no such thing as aluminum chloride gas. There is a gas given off, but it is hydrogen gas. The "smoke" is actually tiny droplets of water condensed from water vapor. It gets that hot. The red color is due to the formation of copper metal a Cu2+ ions are reduced to the metal as aluminum metal is oxidized. Aluminum metal has a thin coating of aluminum oxide, Al2O3, covering the surface. Even freshly scraped aluminum metal will quickly reform the passivating layer of aluminum oxide. So in many solutions, the layer of Al2O3 prevents any aluminum metal from reacting. If aluminum metal is placed in a solution of copper(II) sulfate, you will not get a reaction. No copper metal will form on the aluminum. But when placed in copper(II) chloride, aluminum will give a vigorous reaction with a lot of heat and hydrogen gas being given off. The reason is the chloride ion. In the presence of chloride ion, the Al2O3 layer dissolves forming the AlCl4^- in solution and exposing a fresh layer of aluminum metal. The aluminum metal will reduce copper(II) ions to copper metal, AND the aluminum metal will react with water very much like an alkali metal reacts with water, vigorously, with a lot of heat given off, and with the formation of hydrogen gas. Al2O3 + 8Cl- + 3H2O --> 2AlCl4^- + 6OH- Al(s) + OH- + 2H2O --> Al(OH)3(s) + H2(g) 2Al(s) + 3Cu2+ --> 2Al3+ + 3Cu(s)
Chlorine and copper combine to form either copper(I) chloride, CuCl, or copper(II) chloride, CuCl2. Copper(I) chloride is also called cuprous chloride, and is a white solid that is not very soluble in water. Copper(II) chloride is also called cupric chloride and is a yellowish-brown solid that is soluble in water.Added:Chlorine will make copper to be oxidized. Cupric chloride will be formed.Cu (-2e-) + Cl2 (+2e-) --> CuCl2
2AlBr3 + 3Cl2 -> 2AlCl3 + 3Br2
2Al + 3Cl2 -> 2AlCl3 aluminium reacts with chlorine gas to form aluminium trichloride.
copper!
Surely meant: AlCl3 for aluminum chloride
Al(3+) + Cl(1-) = AlCl3

Copper chloride form ionic bond. Copper exists as cuprous and cupric. It react with chlorine and ionic bonds are formed.

The brown copper(II) chloride absorb water and form the green dihydrate.

Hydrochloric acid will react with Aluminum to form Aluminum Chloride (AlCl3) but not with Nickel.
Chloride ions would form elements with ions of metallic elements. For example, with sodium ions, chloride ions form sodium chloride.
copper nitrate and silver chloride Copper chloride reacts with silver nitrate to form copper nitrate and silver chloride. There are two types of copper chloride compounds. One is copper(I) chloride with the unit formula CuCl, and the other is copper(II) chloride with the unit formula CuCl2. The following are the two chemical equations for the two possible chemical reactions. CuCl + AgNO3 --> CuNO3 + AgCl CuCl2 + AgNO3 --> Cu(NO3)2 + AgCl
I believe that would form aluminum chloride.
