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 is the chemical equation for the reactions when copper is added to aluminum sulfate?
The chemical equation for the reaction when copper is added to aluminum sulfate is: 3Cu + 2Al2(SO4)3 -> 3CuSO4 + 2Al
What happens to the water temperature when calcium chloride is added?
When calcium chloride is added to water, it increases the temperature of the water. This is due to the exothermic reaction that occurs when calcium chloride dissolves in water, releasing heat in the process.
What is the charge on a copper chloride ion?
When a copper ion bonds with chlorine, it bonds with 2 chlorine atoms, because copper has a charge of 2+ (?? cf. Added answer below) and chlorine a charge of 1-So to balance each other, the final formula is CuCl2 one copper ion to two chloride ions. The overall charge on any ionic bond is 0. They bond because they balance each other.Added:Cuprous chloride (Cu(I)-chloride) is sparingly soluble in water, but very soluble in concentrated hydrochloric acid as a complex ion of CuCl2-, in which Cu is +1 charged, and Cl has -1 charge. The white solid crystal is CuClOn Cupric chloride (Cu(II)-chloride) there are many more possible complex ions. for this you are referred to the 'Related links' left below this answer page.
What metal is alloyed with copper to make bronze?
Typically, bronze is an alloy of copper and tin, with copper being the primary component. Other metals such as aluminum, silicon, and manganese can also be added to bronze alloys to alter its properties for specific applications.
What is the maximum mass of aluminum chloride that can be formed when reacting 24.0 g of aluminum with 29.0 g of chlorine?
The gram atomic mass of aluminum is 26.9815; the gram atomic mass of chlorine is 35.453; and the formula of aluminum chloride is AlCl3, showing that three atoms of chlorine are required for each atom of aluminum in the compound. Therefore, mass ratio of chlorine to aluminum in the compound is [3 X (35.453])/26.9815 or 3.942. The ratio of reactant chlorine stated to be available to reactant aluminum stated to be available is 29.0/24.0 or 1.20, so that chlorine is clearly the limiting reactant. Therefore, the mass of aluminum in the maximum mass of aluminum chloride that can be made from the reactants stated is 29.0/3.942 or about 7.357 grams, and that added to the stated 29.0 g of chlorine constitutes 36.4 grams total of aluminum chloride, to the justified number of significant digits.
What happens when you mix copper II chloride in water and then add aluminum folio into the mixture?
When aluminum foil is added to a solution of copper (II) chloride in water, a displacement reaction occurs where the aluminum reacts with the copper (II) ions. This results in the formation of aluminum chloride and copper metal. The copper metal will appear as a solid precipitate in the solution.
What is the aluminum and copper chloride reaction used for?
The reaction between aluminum and copper chloride is often used to demonstrate displacement reactions in chemistry. When aluminum is added to copper chloride, the aluminum will displace the copper in the compound, resulting in the formation of aluminum chloride and copper metal. This reaction is commonly used in educational settings to illustrate the reactivity of metals and the concept of displacement reactions.
What happens to magnesium when you mix aluminum and copper sulfate?
When aluminum is mixed with copper sulfate, the aluminum reacts with the copper ions in the copper sulfate solution and displaces the copper, forming aluminum sulfate and copper metal. Magnesium does not play a direct role in this reaction.
Physical change copper chloride aluminum foil experiment?
When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.
What happens to ferric oxide solution when aluminum chloride is added?
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.
What happens when a piece of copper is added to iron II chloride solution?
When a piece of copper is added to an iron II chloride solution, a single displacement reaction occurs where the copper displaces the iron in the compound. This results in the formation of copper II chloride and iron metal precipitate. The copper atoms give electrons to the iron II ions, causing them to become solid iron.
What happens if hydrochloric acid is added to copper 2 oxide?
