Copper(II) Nitrate is an inorganic chemical with the formula Cu(NO3)2. It occurs as 5 different hydrates, with the most common being the trihydrate and the hexahydrate.
Copper (II) nitrate is prepared in two different ways.
The first method involves nitric acid and produces a hydrated form of the compound even if anhydrous nitric acid is used because the reaction produces water as a bi product
The second method involves Dinitrogen tetroxide. dinitrogen tetroxide is produced by cooling nitrogen dioxide below 25 °C. This produces anhydrous copper nitrate as long as water is kept separated from the final product and from the reaction. adding water to dinitrogen tetroxide produces nitric acid and nitrous acid.
