N2O5 compound name is dinitrogen pentoxide.

Hello, reders welcome to another fresh article on “textilesgreen.in” today we will discuss about dinitrogen pentoxide.

We will provide valuable information regarding this topic.

So, hold your seat end of out and read complete article.

What is N2O5?

You know that dinitrogen pentoxide is a chemical compound. the chemical formula of dinitrogen pentoxide is N2O5. and the symbolic form is also be N2O5.

it is prepared with the help of conc nitric acid (HNO3) and pohphours pentoxide (p4 O10).

When 4 mole of nitric acid react with P4O10 the it is given 2 mole of dinitrogen and 4 mole of HPO3.

4 HNO3 + P4 O10 – 2 N2O5 + 4 HPO3

Where,

N2O5 – Dinitrogen pentoxide &

HPO3 – pohphours

the final products is produce, 2 mole of N2O5 + 4 mole of HPO3.

Also prepared;

When 2 mole of nitric acid react with P2O5 then it produce dinitrogen pentoxide and 2 mole of HPO3.

2HNO3 + P2O5 – N2O5 + 2HPO3

In this case, the final products is, dinitrogen pentoxide and 2 mole of HPO3.

it is produce white crystals by oxidizing nitric acid (HNO3) with ozone. it is unstable chemical compound in which it decompose at room temperature with nitrogen dioxide and water.

It is also called as nitric anhydride.

N2O5 structure

n2o5 structure

it is a crystal structure – (hexagonal)

the molecular shape of dinitrogen pentoxide is planner.

if you see on structure of dinitrogen pentoxide with very carefully then you can write the above information regarding this structure of chemical compound.

Such as,

1. Total atoms – 7

2. Total valence electron – 10 + 30 = 40

3. Required for octen = 56

4. Lacking = required for octen – total valence electron (56 – 40 ) = 16

So, the lacking = 16

5. total number of bond = 16/2 = 8 bond

These are the basic information regarding this structure. this is very important to remember for examination purpose.

N2O5 Properties;

Physical properties

2. N2O5 is highly acidic.

3. Boiling point – 47°C

4. Melting point – 41°C

5. Density – 1.64 g/ cm3

6. Molar Mass – 108.01 g/mole

7. Chemical formula – N2O5.

Chemical properties

1. when 4 mole of AgNO3 is react with 2 mole of Cl then it is given 2 mole of dinitrogen and O2

4 AgNO3 + 2Cl – 2N2O5 + O2

2. When 2 mole of dinitrogen pentoxide is heated then it produce 2 mole of N2O4 and O2.

2N2O5 (Heat) – 2 N2O4 + O2

3. When N2O5 react with water (h2o) then it is given nitric acid (HNO3).

N2O2 + H2O – HNO3 + O2

4. When hno3 nitric acid is heated in the presence of H2O then it is directly given dinitrogen pentoxide is as a product.

Reaction is,

2 HNO3 [Heat] (-H2O) – N2O5

Uses of N2O2 (dinitrogen pentoxide)

• it is used as a solvent for nitrated water sample.

• you know that, dinitrogen pentoxide and HNO3 is called as nitrating agent. It is used in synthetic organic chemistry.

• it is used as a strong nitrating agent.
