Copper II Nitrate Formula

The formula of Copper II Nitrate is Cu(NO3)2. It is an organic compound with an appearance of a blue crystalline solid. 

Anhydrous copper nitrate forms dark blue-green gems and sublimes in a vacuum at 150-200 °C. Copper nitrate additionally happens as five different hydrates, the most widely recognized ones are copper II nitrate hemipentahydrate hemipentahydrate, and Copper II nitrate trihydrate.

The chemical formula of copper nitrate comes along with various properties, which we will discuss on this page.

Besides the chemical formula for copper nitrate, we will focus on the formula of cupric nitrate, and copper II nitrate trihydrate formula.

Now, let’s understand the structure in words:

Formula of Cupric Nitrate

A synthesis and reaction for copper nitrate aqueous solution of copper (II) nitrate occur in the following way:

Hydrated copper nitrate (cupric nitrate) formation occurs by hydration of the anhydrous material or by treating copper metal with an aqueous solution of silver nitrate or concentrated nitric acid (HNO3):

           Cu (s)      +        4 HNO3 (l)     →   Cu(NO3)2 (s)      +          2 H2O (l)    +     2 NO2 (g)

       Copper metal   Nitric Acid      Copper II Nitrate   Water          Nitrogen Dioxide

The cupric nitrate formula has a particular geometry that we’ll discuss in the following section:

Formula for Copper II Nitrate

Copper II Nitrate formula is also known as the cupric nitrate formula. The cupric nitrate is a glistening and attractive colour blue-green inorganic salt.

In the above image, an isolated molecule of Cu(NO3)2 is represented in the gas phase.

Besides this, the oxygen atoms of the nitrate anion coordinate instantly with the copper center (internal coordination sphere), and therefore, forming four Cu - O bonds.

Cu(NO3)2  or the formula of copper II nitrate has a square plane molecular geometry. The plane is shown by the red spheres at the vertices and the copper sphere in the center. The gas-phase interactions are very weak because of the electrostatic repulsions between the NO3 – groups.

Therefore, in the solid phase, the copper centers/habitats metallic bonds – Cu – Cu – to create polymeric copper chains.

Water molecules can form hydrogen bonds with NO3 – groups and these offer hydrogen bonds for other water molecules and until the water sphere forms around Cu(NO3)2.

In this sphere, you have one to six external neighbors; hence the salt gets easily hydrated to generate the hydrated tri and hexa salts.

The salt formed from one Cu2+ ion and two NO3- ions gives it a characteristic crystallinity of ionic compounds (orthorhombic structure for anhydrous salt and rhombohedral for hydrated salts). However, the bonds are mostly covalent in nature.

Please Note:

Other than copper nitrate formula, we have copper 1 nitrate formula a.k.a cuprous nitrate formula), and the copper ii nitrate trihydrate formula; let’s have a look at these:

Copper I Nitrate Formula

Copper (I) nitrate is also known as cuprous nitrate. The copper 1 nitrate formula is a molecular formula of CuNO 3. 

CuNO 3 is also known as cuprous nitrate formula.

It is a compound with copper in a + 1 oxidation state. Complexes comprising cuprous nitrate are countless and involve compounds like triphenylphosphine, triphenylstibine, and triphenyl arsine.

Copper II Nitrate Trihydrate Formula

The Copper II Nitrate Trihydrate Formula is (CuNO3)2. 3H2O. Its structure looks like the following:

From the above Copper II Nitrate Trihydrate structure, we see that Copper II Nitrate Trihydrate Formula is the formula for copper II nitrate with three moles of released water.

Conclusion

The formula of cupric nitrate and Cuprous nitrate formula vary in their oxidation states, i.e., Cu has a + 2 and + 1, respectively. However, in copper II nitrate trihydrate also, Cu has + 2 oxidation with an additional 3 moles of water.
