Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu(NO 3) 2 (H 2 O) x. The hydrates are hygroscopic blue solids. Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C. [5] [6] Common hydrates are the hemipentahydrate and trihydrate.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
Many other oxyanions form complexes; these include copper(II) acetate, copper(II) nitrate, and copper(II) carbonate. Copper(II) sulfate forms a blue crystalline pentahydrate, the most familiar copper compound in the laboratory. It is used in a fungicide called the Bordeaux mixture.

Various anhydrous transition metal nitrate complexes can be prepared from N 2 O 4 and base metal. [24] 2 N 2 O 4 + M → 2 NO + M(NO 3) 2. where M = Cu, Zn, or Sn. If metal nitrates are prepared from N 2 O 4 in completely anhydrous conditions, a range of covalent metal nitrates can be formed with many transition metals. This is because there is ...

In numerous variants that have been developed, other transition metal salts, including copper(II), iron(III) and cobalt(III) have also been employed. [7] Due to its wide synthetic applicability, the Sandmeyer reaction, along with other transformations of diazonium compounds, is complementary to electrophilic aromatic substitution .
