When a current is passed through a U-tube whose lower half 

 is filled with cupric sulphate solution, while both arms are filled 

 with sodium sulphate solution into which the electrodes are

 salt, the blue color moves toward the anode, as the copper is 

 contained for the most part in complex anions.
