Question

What will you observe when a few Copper pieces are added to a solution of Ferrous Sulphate

Answer 1

• When a few pieces of Copper are added to Iron Sulphate solution there will be no change and no reaction will be observed.
• This is because Copper is less reactive than Iron, therefore, Copper will be unable to displace Iron from its solution.

$$\begin{gathered} \mathbf{Cu}\mathbf{}\mathbf{\left(}\mathbf{s}\mathbf{\right)}\mathbf{}\mathbf{+}\mathbf{}{\mathbf{FeSO}}_{\mathbf{4}}\mathbf{}\mathbf{\left(}\mathbf{aq}\mathbf{\right)}\mathbf{}\mathbf{\to }\mathbf{}\mathbf{No}\mathbf{}\mathbf{reaction} \\ \mathbf{Copper}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{Iron}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{Sulphate}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{} \end{gathered}$$

• Hence, no reaction will observe when a few Copper pieces are added to a solution of Ferrous Sulphate.
