Just got a new '11 GTI and trying to teach my GF a stick shift â on the hills of SF. She's been stalling the car quite a lot.
Answers. Best Answer: Copper Nitrate forms blue crystals which dissolve in water. Transition metal salts often form colored crystals. Since the other reaction product is metallic silver precipitate, and everyone knows what silver looks like, the blue is from the copper nitrate by process of elimination.The original solution was not blue because silver nitrate is colorless/slight gray when in solution and Cu(s) is just copper metal.ince the other reaction product is metallic silver precipitate, and everyone knows what silver looks like, the blue is from the copper nitrate by process of elimination.
If you heat the copper slowly, the water will evaporate, but the copper will not be heated to the point where it reacts with the oxygen in the air (combust).If you heat it quickly, the copper will heated so intensely that it reacts with oxygen to form the copper (2) oxide compound.Therefore, you will not have pure copper, but look on the bright side, the water's gone. denwel33 Â· 7 years ago.
