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.
anhydrous copper sulfate is whitish to grayish. anhydrous meaning it has no water molecules binding to it. it turns blue because copper becomes sort of a complex ion by binding to water. the blue powder are copper sulfate crystals. try en.wikipedia.org and search copper sulfate.n case of copper sulfate when they are hydrated the blue colour is due to the presence of Cu++ ions. When all the water molecules has been lost no water molecule is remained that's why it becomes white. Source(s): jai Â· 9 years ago.
