When NH3 is added to a solution that contains Cu2+ ions at first the solution becomes cloudy and a white precipitate starts to fall to the bottom of the container. If NH3 continues to be added the solution changes from a light blue color to a dark blue color and the precipitate disappears. Describe what is happening is happening on the molecular level.
