I've personally done this experiment, and although it looks like the aluminum is dissolving, the ionic bonds are breaking and causing the foil to decompose.
Please someone answer a question for CuSO4 + H2O+Al= What when added to Cupric Sulfate and Cupric Chloride? Need this for a science class!!
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.
Ferric oxide (Fe2O3) is not soluble in water.
The reaction forms aluminum sulfate and frees copper.
I think it turns from brown to a silver color
because of the copper ions
No. Table salt is sodium chloride. If it is iodized it has iodine added, but no aluminum.
Copper turnings react with HCl to form Copper chloride and give out hydrogen gas. Cu(s) + 2HCl -----> CuCl2 +H2(g)
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
The chemical equation for the reaction that occurs when zinc metal is added to a solution of copper II chloride is: Zn + CuCl2 -> Cu + ZnCl2.
when aluminium is added to dil. hcl it forms aluminium chloride and hydrogen gas. 4 Al + +6 HCL=2 Al2CO3 + 3 H2
Silver chloride is not soluble in water.
silver chloride should precipitate out.
Sodium chloride is easily dissolved.
Rubidium chloride is dissolved and dissociated in water.
There is no reaction at all.
When you mix the solutions of Sodium Hydroxide and barium chloride then a double replecement occurs.2 NaOH + BaCl2 = 2 NaCl + Ba(OH)2
You will obtain a sodium chloride solution in water.
Uranium doesn't react with copper.
Copper is deposed on the steel wool.
Your products will be Potassium nitrate and silver chloride
It becomes Barium Nitrate combined with Silver Chloride
Zinc is higher up the reactivity series than copper, so when copper is added to zinc sulphate solution, nothing happens. If zinc had been added to copper sulphate solution, then copper would have been produced and zinc would have dissolved to form zinc sulphate.
