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 (more electro positive) than iron. Therefore, Zinc displaces Iron from its salt solution. The colour of ferrous sulphate is pale green, which turns colourless.

FeSO₄ + Zn → ZnSO₄ + Fe_(s)
