- End Product Cu = 0.679 g

Observations:
· The copper at the beginning was a light reddish and powdery solid.
· When the HNO3 was added, the liquid turned green and produced an orange gas (NO2 (g)). There was a grainy substance on the bottom. There was no change in temperature.
· When the NO2 was gone, the solution still smoked.
· When we added the water, the solution went from a green to a very crystal, pretty blue. The substance stopped smoking and the grainy substance at the bottom went away, it dissolved. There was no change in temperature.
· After the NaOH was added, the solution turned a more vibrant and bright blue and had almost a jelly look to it. The......
