Why does the colour of copper sulphate solution change when an iron nail is dipped in it?

Text Solution

Verified by Experts

Iron is more reactive than copper. It displaces copper from copper sulphate solution according to the following reaction:
`underset("Iron")(Fe(s))+underset("Copper sulphate")(CuSO_(4)(aq))rarrunderset("Iron (II) sulphate")(FeSO_(4)(aq))+underset("Copper")(Cu(s))`
Thus, as copper sulphate reacts to form iron(II) sulphate, the blue colour of copper sulphate solution fades.
