What would you observe when zinc is added to a solution of iron(II) sulphate? Write the chemical reaction that takes place.

Zinc is more reactive than Iron. When Zn is added to Iron (II) Sulphate, Zinc displaces Iron from its solutions and Zinc sulphate is formed.
Zn(s) + FeSO₄(aq) → ZnSO₄(aq) + Cu(s)

Zinc is more reactive than iron. Therefore, when zinc is added to a solution of iron (II) sulphate, then it would displace iron from the solution.
Zn + FeSO4 → ZnSO4 + Fe
When zinc is added to a solution of iron(II) sulfate (FeSO₄), a displacement reaction occurs. Zinc is more reactive than iron, so it displaces iron from the compound. The chemical reaction can be represented as follows:
Zn(s) + FeSO₄ (aq) → ZnSO₄(aq)+Fe (s)
In words, zinc reacts with iron(II) sulfate to form zinc sulfate and elemental iron. The appearance of elemental iron may be observed as a change in color or the formation of a precipitate in the solution. The zinc sulfate formed remains in solution.
