• When zinc is introduced to an iron sulphate solution, the colour of the iron sulphate solution changes. Since zinc is more reactive than iron, it displaces iron from its iron sulphate solution, resulting in a grey precipitate of iron and a colourless zinc sulphate solution.The chemical equation of the reaction,
• Zn + FeSO4 → ZnSO4 + Fe
