Copper II Nitrate Formula

Copper II Nitrate Formula

Copper ll nitrate is one of the inorganic compounds with the chemical formula Cu(NO3)2. Another name for copper ll nitrate is Cupric nitrate. It forms as dark blue-green gems and sublimes in a vacuum. 

About the Topic

The molar mass of Copper ll nitrate is 187.5558 g/mol (anhydrous), 241.60 g/mol (trihydrate), 232.591 g/mol (hemipentahydrate).

The appearance of copper ll nitrate is that blue crystals are hygroscopic. The melting point is 114 °C, and the boiling point is 170°C. Copper II nitrate is 138 g/100 mL (0 °C) trihydrate soluble in water. 

Copper ll nitrate is prepared from metallic Copper treated with nitric acid. One of the other varieties of copper II nitrate is anhydrous Copper (II) nitrate is mainly one of the few anhydrous transition metal nitrates which can’t be prepared just by reaction of water; it only gets produced when copper metal is treated with dinitrogen tetroxide. 

Cu + 4HNO3 → Cu(NO3)2 + 2H2O + 2NO2

It can also be produced by treating metallic Copper with dinitrogen tetroxide. The density of copper ll nitrate is 3.05 g ml-1 (anhydrous). 

Cu + 4HNO3 → Cu(NO3)2 + 2H2O + 2NO2

Cu + 2N2O4 → Cu(NO3)2 + 2NO

There are very rare natural occurring systems of copper II nitrate like minerals gerhardtite and rouaite, both being polymorphs of Cu2(NO3)(OH)3 substance.

Copper II nitrate is mainly used to produce pyrotechnic and blue colours and coats. It is used as a classical demonstration of the voltaic cell and produces copper (II) oxide from copper II nitrate.

Copper nitrates are found in pyrotechnics and are mostly used in school laboratories to demonstrate chemicals and their voltaic cell reactions.

Formula

Cu(NO3)2

Solved Examples

• What is the molecular weight of Copper II Nitrate with a solved formula?

Copper II nitrate mainly consists of 1 Copper atom, 2 Nitrogen, and 6 Oxygen atoms.

Which means 

The atomic weight of Copper = 63.546

The atomic weight of each Nitrogen = 14.0067 

The atomic weight of each Oxygen = 15.999 

After adding all three substances 

The molecular weight of Cu(NO3)2 = 63.546 + (2 × 14.0067) + (6 × 15.999)

We get 187.55 as a molecular weight of copper II nitrate.

• What is the chemical structure of Copper II nitrate?

The chemical formula of the compound Copper II Nitrate is Cu(NO3)2, and it is prepared with the reaction of Copper metal and Nitric Acid. 

Cu + 4HNO3 Cu(NO3)2 + 2H2O + 2NO2.
