Copper is deposited on the surface. This is an example of a single displacement reaction.
Fe +CuSO4 -> Cu +FeSO4
the solution which started as blue (copper sulphate) becomes paler as the Copper ions, Cu2+ are replaced by ferrous ions, Fe2+
Iron is higher in the reactivity series than copper.

Can you reverse an iron nail rusting?
ca you reverse an iron nail rusting
Is iron in cereals the same as iron in a nail?
Yes but it is present as a compound rather than as pure metallic iron.The red colour of blood is caused by an iron compound (hemoglobin) and this is why you need to eat sources of iron.
Is a nail iron?
An iron nail is an object used to hammer things in with, boof, or boof boof
Explain why the mass of a rusted nail would be greater than the mass of the nail before it rusted Assume that all the rust is still attatched to the nail?
Rust is a compound of iron and oxygen. Therefore the mass is greater because oxygen has been added.
Does rust increase the weight of a nail?
The rusty nail weighs more. Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
What happen when an iron nail is added to some cooper sulphate solution?
The chemical reaction is:Fe + CuSO4 = FeSO4 + Cu
What will happen to iron nail kept in cuso4 solution for 2 to 4 hrs?
A copper film is deposed on the iron nail.
When the iron nail is placed in copper sulphate solutiondoes the nail become iron?
If an iron nail is placed in a copper(II) sulfate solution, the iron ions are exchanged with the copper ions, creating iron sulfate and copper (which precipitates out as copper metal). Fe + CuSO4 --> FeSO4 + Cu
What is the difference between iron and iron nail?
Iron is a compound iron nail is a iron ore which means that the iron nail is a mixture of metals such as copper and zinc added to make the nail stronger.
What happens when an iron nail is dipped in copper sulphate solution?
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)
Why does the color of copper sulphate change when an iron nail 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.
When iron nail is put into a beaker containing copper sulphate solution the blue colour of solution turns green why?
Iron is more reactive than copper and the ferrous (Fe++) ions will replace the copper (Cu++) ions in the sulphate. CuSO4 is blue, FeSO4 is green.
Do Iron in nail polish remover melts?
Yes!iron melts when added to the nail polish remover.
When an iron nail is dipped into copper sulphate solution after sometime the colour is changed into?
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
What happen when you put an iron nail into iron sulphate?
iron(Fe) being more reactive than Copper(Cu) displaces Cu from copper sulphate (CuSO4). Thus, the following equation is derived:Fe + CuSO4 -----> FeSO4 + CuOBSERVATIONS-1. reddish-brown deposit on the surface of nail2. surface of the nail is found corroded3. the blue solution turns light green
Why colour of copper sulphate solution changes to light green when iron filings are added?
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.
What are the properties of iron nail?
Five physical properties of an iron nail are: Solid Metallic luster Malleable definite melting point gray colour
