Reaction:
The ferrous sulfate solution will react with the aluminum can, leading to the formation of aluminum sulfate (Al₂(SO₄)₃) and metallic iron (Fe). This reaction is a single displacement reaction, where the more reactive aluminum replaces the iron in the ferrous sulfate.
Chemical Equation:
3FeSO₄(aq) + 2Al(s) → Al₂(SO₄)₃(aq) + 3Fe(s)
Consequences:
* Corrosion of the Aluminum Can: The aluminum can will corrode as it reacts with the ferrous sulfate solution. This corrosion can weaken the can and lead to leaks or even complete failure.
* Formation of Iron Deposits: The iron formed in the reaction will deposit on the inside of the can. These iron deposits can impact the quality of the ferrous sulfate solution, potentially leading to contamination.
* Release of Hydrogen Gas: In some cases, the reaction can also produce hydrogen gas. This gas is flammable and could pose a safety hazard if it builds up inside the can.
* Discoloration of the Solution: The ferrous sulfate solution may become discolored due to the presence of iron deposits and other reaction products.
Conclusion:
Storing ferrous sulfate solution in an aluminum can is not recommended due to the chemical reaction that occurs, leading to corrosion, contamination, and potential safety hazards. It is best to store ferrous sulfate solutions in containers made of materials that are not reactive with the solution, such as glass or plastic.
