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

solution:
Zinc is more reactive than iron. Therefore, if zinc is added to a solution of iron (II) sulphate, then it would displace iron from the solution and green colour of $\mathrm{FeSO}_{4}$ solution will fade.

$\mathrm{Zn}(\mathrm{s})+\mathrm{FeSO}_{4}(\mathrm{aq}) \rightarrow \mathrm{ZnSO}_{4}(\mathrm{aq})+\mathrm{Fe}(\mathrm{s})$
