|(aq)||aqueous (dissolved in water)|
An iron nail is placed in a solution of blue copper(II) sulfate. Over time, a brown solid appears and the solution becomes colourless. This is because copper and a solution of iron(II) sulfate forms.
Add state symbols to the balanced chemical equation for the reaction of iron with copper(II) sulfate.
Fe + CuSO4 → FeSO4 + Cu
Fe(s) + CuSO4(aq) → FeSO4(aq)+ Cu(s)
