What are the sources of error in a aluminum and copper II chloride dihydrate?

-scale not having enough sig figs when measuring
-the copper chloride oxidizing before and after reaction (adding mass)
-white residue of chloride left as precipitate (adds mass to copper when filtered)

Copper II chloride aluminum?
AlCl3+Cu
What do copper II chloride and aluminum form when combined?
Copper, Aluminum Chloride, and Heat. Improve: 2Al (s) + 3CuCl2 (aq) --> 3Cu (s) + 2AlCl3 (aq)
Copper chloride aluminum foil physical change?

What happens when aluminum is added to water and copper chloride?
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.
What scientific conclusion can be made about combining Copper Chloride and Aluminum Foil?
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)
Why does copper chloride turn green?
The brown copper(II) chloride absorb water and form the green dihydrate.
What do copper chloride and aluminum form when combined?
copper!
What is a balanced chemical equation for HCl Cu?
Copper Chloride Hexahydrate
Copper II chloride aluminum?
AlCl3+Cu
Is a copper chloride solution blue?
Yes. The dihydrate is a light blue-green. Solutions are a pale blue-green in color.
What do copper II chloride and aluminum form when combined?
Copper, Aluminum Chloride, and Heat. Improve: 2Al (s) + 3CuCl2 (aq) --> 3Cu (s) + 2AlCl3 (aq)
How do you write the name for CaCl2.2H2O?
Calcium Chloride is the formula name for CaCl2.
What is the formula of Copper II Sulfite Dihydrate?
The chemical formula for the compound Copper (II) Sulfite Dihydrate is:CuSO3.2H2O
When combining Aluminum and Copper Chloride what material is formed?
Two materials are formed: metallic copper and aluminum chloride. This is an example of displacement of a less active metal from its compounds by a more active metal in the electromotive series.
Which element is blue in aqueous state?
Aqueous isn't a "state". Oxygen is a very, very pale blue in the liquid state; could that be what you're thinking of?
What if you don't wait for the copper to reduce in a copper chloride reaction with aluminum?
Then you just go by your own given name.
