An aluminium can was used to store ferrous sulphate solution. It is observed that in a few days,holes appeared in the can. Explain the observation and write the chemical equation to support your answer.
(N/A) Aluminium is more reactive than iron. Therefore,it displaces iron from the ferrous sulphate solution in a displacement reaction.
The chemical reaction is as follows:
$2Al(s) + 3FeSO_4(aq) \to Al_2(SO_4)_3(aq) + 3Fe(s)$
Due to this reaction,the aluminium metal of the can is consumed to form aluminium sulphate,which leads to the formation of holes in the can.
The chemical reaction is as follows:
$2Al(s) + 3FeSO_4(aq) \to Al_2(SO_4)_3(aq) + 3Fe(s)$
