Iron is displaced from ferrous sulphate solution by aluminium, being very reactive. So, the can gets damaged due to this.
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)
the aluminium is split with the sulphate ion. this leaves the sulphate on its own with a charge. the copper then takes the place of the aluminium turning the charge of the sulphate ion to neutral, this leaves the aluminium and copper sulphate.

What is the metal cation that gives the 'green' colour.
aluminium sulphate solution rects with sodium bicarbonate to give aluminium hydroxide, sodium sulphate and carbon dioxide. Al2(SO4)3 +6 NaHCO3 = 3 Na2SO4 + 2Al(OH)3 + 6 CO2 This reaction can be seen in a foam based fire extinguisher
Aluminium is more reactive than iron (Fe) according to the reactivity series of metals. Thus, when Ferrous Sulphate solution is stored in Aluminium can, Aluminium being more reactive, displaces iron from its solution to form Aluminium sulphate and iron. :)
The chemical reaction is:Fe + CuSO4 = FeSO4 + Cu

Al2(SO4)3 or Al2O12S3
Formula: Al2(SO4)3

The solution of aluminium sulfate may be stored an indefinitely period.
