When an iron nail is placed into a solution of copper sulfate?

no reaction occurs


iron (II) chloride is formed


iron copper sulfate is formed


the iron replaces the copperWhen an iron nail is placed into a solution of copper sulfate?
Fe (nail) + CuSO4 --%26gt; FeSO4 + Cu





it stands to reason that the iron replaces the copper. There definitely is a reaction; there is no chloride, so iron CHLORIDE cannot form. There is no reason to think that iron copper sulfate is formed.When an iron nail is placed into a solution of copper sulfate?
theiron replaces the copper in solution and copper precipitates
In the reactivity series Iron is placed aboce copper.It is the chemical property of metal that when a more reactive metal is placed in the salt solution of a less reactive metal it replaces the less reactive metal so iron will replace copper.





Fe + CuSO4-------Cu + FeSO4





On the other hand if we see the RHS of the equation their would be no reaction because Cu is less reactive than Fe.





Cu + FeSO4------No Reaction
