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.
Copper turns green because of an oxidation reaction; that is, it loses electrons when exposed to water and air. The resulting copper oxide is a dull green. This oxidation reaction is the reason the copper-plated Statue of Liberty is green rather than orange-red. According to the Copper Development Association, a weathered layer of copper oxide only 0.005 inches (0.127 millimeters) thick coats Lady Liberty.
