* Tin is more reactive than iron: Tin is higher in the reactivity series than iron. This means it has a greater tendency to lose electrons and form positive ions.

* Displacement reaction: When tin is placed in a solution of iron sulfate, a displacement reaction occurs. Tin will displace iron from the solution, forming tin sulfate and metallic iron.

The reaction can be represented by the following chemical equation:

Sn(s) + FeSO₄(aq) → SnSO₄(aq) + Fe(s)

Observations:

* You would see the formation of a grayish-black deposit of metallic iron on the surface of the tin.

* The solution would gradually change color from pale green (iron sulfate) to colorless (tin sulfate).

Important Note: The reaction may take some time to become noticeable, as the rate of reaction depends on factors such as temperature, concentration, and surface area.
