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 oxidizes whereby it turns Blue / Green. Oxidation is a phenomenon whereby an element loses electrons (and/or hydrogen) on interacting with another element. There are many examples of oxidation, which we observe in our day-to-day life.t is to be noted that copper does not react with water. The outer green layer, formed after the oxidation of copper, is known as patina. Unlike other destructive oxidation, patina acts as a protective layer. This is the reason as to why, copper is considered as an important metal, resistant to corrosion.
