It turns a green colour
Any water soluble blue salt (and which does not react with water) can turn the solution blue. For example = Copper(II) sulfate[CuSO4], Oxovanadium(IV) sulfate[VOSO4], Copper(II) nitrate[Cu(NO3)2], etc.
If thou mean copper II nitrate (with two I's) it will turn white as it is converted from a hydrated to an anhydrous salt.
Copper chloride makes fire blue.
Crimson Red
The penny turned silver color due to a process called oxidization. Over time, the copper in the penny reacts with oxygen in the air to form copper oxide, which appears silver in color.
Lead nitrate is colorless, as are zinc ions. So it doesn't "turn into" any color.
the silver is displaced out of the compound because the copper is more reactive. It becomes copper nitrate.
Strontium nitrate will turn a flame red
Any water soluble blue salt (and which does not react with water) can turn the solution blue. For example = Copper(II) sulfate[CuSO4], Oxovanadium(IV) sulfate[VOSO4], Copper(II) nitrate[Cu(NO3)2], etc.
When testing silver nitrate, a whitish color will yield positive results. If the test is negative, the color will turn clear and it will remain transparent.
Copper(II) nitrate crystals will began to bubble and melt very quickly. After a short period of time, it will begin to glow, and it will turn green. gas was forming.
If thou mean copper II nitrate (with two I's) it will turn white as it is converted from a hydrated to an anhydrous salt.
Turquoise
Copper chloride makes fire blue.
Acid in the rain reacted with the copper to turn it green. That is why there is sometimes green on pennies. Acid in the rain reacted with the copper to turn it green.

The substance in the air is oxygen. Copper + oxygen= copper oxide.
Because of what its made of -.- stupid
