Description

Numerous gases are present in our environment. But do you know which gas makes up the majority of the composition? It is nitrous oxide. If we go into the specifics of the makeup of the atmosphere, it is made up of 78% nitrogen, 21% oxygen, 1% argon, and minute amounts of carbon dioxide, krypton, and hydrogen.

 

  • Nitrogen gas has two molecules of Nitrogen therefore, the molecular formula of this gas is N2. It is a non-metallic element that occupies Group 15 of the periodic table. 
  • Nitrogen gas is colorless, odorless, and tasteless, which was discovered by a well-known scientist named Daniel Rutherford in 1772. 
  • However, its name was derived from the Greek words ‘nitrogen’ and ‘genes’ which means niter forming.

 

Properties of Nitrogen Gas:

Like any other state of matter exhibits both physical and chemical properties, Nitrogen gas also tends to exhibit the same. Therefore, the atomic weight of Nitrogen is 7, while its atomic weight is 14.0067. The melting and the boiling point of Nitrogen gas are −209.86 °C (−345.8 °F) and 195.8 °C (−320.4 °F), respectively.

 

The density of the gas is 1.2506 grams/liter. In addition to this, the most significant part of nitrogen gas is that the triple bond between the atoms of the gaseous molecule is so strong that it does not allow any other molecule to enter their combinations.

 

Uses of Nitrogen Gas:

  • Since nitrogen gas is a noble or an inert gas, we can use it to diminish or minimize the oxidation of various materials. More abundantly, we use it for the production of ammonia, which we use as a fertilizer, explosive, or various other materials.
  • Not just that, we all have heard about liquid Nitrogen. Liquid Nitrogen is an excellent refrigerant that freezes things to relatively low temperatures. Thus, hospitals use it to preserve blood. Also, we use it as a coolant for large computer systems.
  • We use it as a disinfectant for household purposes. Commercially, the plastic industry uses it as a feed supplement for livestock. Therefore, being abundant in the Earth’s atmosphere, it is equally essential for the sustainability of the environment.

 

Direction of use:

For the safe use of nitrogen, ensure proper ventilation in the workspace due to its inert nature. Connect the nitrogen cylinder to equipment requiring an inert atmosphere or as a pressure source. Handle with care to prevent leaks and avoid exposing it to open flames or ignition sources, as nitrogen is non-combustible.
