We added water to the Copper (II) Oxide solution. Then, using the stirring rod, we decanted the Copper (III) Oxide || || Large percent of copper is lost during this step.

At first we did not see any change, however, as we continued to stir, it started to lose the dark brownish black colour and slowly started to change in to light, clear blue colour.
