It is an electrochemical reaction. Iron is more reactive than copper, meaning it is more easily loses electrons to form a compound. So the copper essentially "steals" electrons from the iron. Forming copper metal and iron sulfate.
It may seem like the iron rusts, but it doesn't. The chemical formula for copper sulfate is CuSO4, or, 1 copper atom, 1 sulfur atom, and 4 oxygen atoms to each molecule. When the iron is placed in the solution of copper sulfate, it replaces the copper in the solution, turning copper sulfate into iron sulfate (FeSO4) and pure copper collects on the iron. This can be proved by removing the copper and seeing that the iron has lost a lot of its mass, as in, it lost mass to the copper sulfate. The iron (steel wool) takes on a pinkish color which is metallic copper deposited when the solution forms iron sulfate.
The anhydrous copper(II) sulfate is white, the pentahydrate is blue.Iron is gray.
There would be no reaction because copper is a less reactive metal than iron. Refer to the related link for an activity series of metals.
Copper sulphate is a blue coloured solution. As soon as you react it with iron, you will notice that the solution is turning into light green which means iron sulphate solution is forming. Iron being more reactive than copper displaces copper from its soluion.
it is because iron is solid and can easily sublimes in aqueous copper sulphate
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.
Iron will not deposit onto a copper plate when it is dipped in iron sulfate because copper has a lower reactivity than iron. In a displacement reaction, a more reactive metal will displace a less reactive metal from its compound. In this case, since iron is more reactive than copper, it displaces copper in the iron sulfate solution forming iron sulfate and preventing the deposition of iron on the copper plate.
When an iron nail is dipped in the solution of copper sulphate solution , after a while the solution changes into the colour of green becoming iron sulphate and a brown substance is found on the iron nail which is copper so we get to know that the displacement reaction is produced
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
When an iron nail is dipped in copper sulfate solution, a displacement reaction occurs. Iron is more reactive than copper, so it displaces copper in the solution and forms iron sulfate. This reaction causes the color change from blue (copper sulfate) to green (iron sulfate) as the copper ions are replaced by iron ions in the solution.
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
It may seem like the iron rusts, but it doesn't. The chemical formula for copper sulfate is CuSO4, or, 1 copper atom, 1 sulfur atom, and 4 oxygen atoms to each molecule.

The iron (steel wool) takes on a pinkish color which is metallic copper deposited when the solution forms iron sulfate.
When copper wire is dipped in ferrous sulfate solution, a displacement reaction occurs where copper displaces iron from ferrous sulfate, forming copper sulfate and iron. As a result, the copper wire will become coated with a reddish-brown deposit of iron.
Iron(Fe) + Copper Sulphate(CuSO4) → Iron Sulphate(Fe2SO4) + Copper(Cu)[Displacement Reaction]
The iron is more reactive than copper so when the iron nail is immersed in copper sulphate the iron takes sulphate ion from the copper sulphate and copper metal is deposited on top of the iron so that the nail will then look like a copper nail.The chemical reaction is called a replacement reaction, and is chemically represented as : CuSO4(compound in solution) + Fe(metal) ------>Cu(deposited metal) + FeSO4.
