Question

what changes do you observe in the iron nails and color of copper sulphate solution, if iron nails are dipped in copper sulphate solution for 15 minutes?​

Answer 1

If iron nails are dipped in copper sulphate solution, the colour of the solution changes from blue to green and a layer of copper is deposited on the iron nail giving a reddish brown colour.

This happens due to the following reaction :CuSO4 + Fe ------> FeSO4 + Cu

Fe displaces Cu from its solution because Fe is more reactive than Cu.
