conclusion is
Iron in nail displaces copper from the copper sulphate solution. As a result, solution fades in
colour.
This displacement reaction results in the formation of elemental copper. Elemental copper deposits on the nail and impart a brown colour to the nail.
CuSO4(aq) + Fe(s) ——-> FeSO4(aq) + Cu(s)
Note: The faded blue apperance later change to green colour because ferrous sulphate is green.
