Properties
Copper(II) nitrate is a blue solid. It is an oxidizing agent. It is blue whether it contains water (hydrated) or not (anhydrous). It makes nitrogen dioxide when it is heated.
Preparation
It is made by reacting copper with nitrogen tetroxide. It can also be made by reacting copper with nitric acid or silver nitrate.
Uses
It can be used to make nitric acid by heating it. Then the brown gas made is dissolved in water to make nitric acid. It can be used to add nitrate ions to organic chemicals.
