What is Nitrogen? and functions, uses and properties of nitrogen, 12th

Functions, uses and properties of nitrogen, and what is nitrogen? Nitrogen was discovered in 1972 by Daniel Rutherford. They achieved this by removing carbon dioxide from the gases exhaled by animals.

The need of this nitrogen gas is very necessary for plants as well as humans, so let us know what is this gas and what is its use.

What is Nitrogen? about this

  • The chemical formula of nitrogen gas is N.
  • This gas is colourless, odorless and tasteless.
  • Nitrogen gas constitutes 78% of the Earth’s entire atmosphere.
  • This gas was discovered in 1973 by Scottish scientist Rutherford.

When this gas was discovered, its name was azote, then it was changed to nitrogen in the year 1790.

Advantages of Nitrogen

Nitrogen is very important for our body, we get it from vegetables, vegetarian and non-vegetarian food, but plants and trees also get nitrogen from the soil.

12th, Chemistry, Lesson-7

The most important thing is that due to nitrogen, nucleic acids i.e. DNA and RNA are formed in our body, which is very important for humans and this food is very much needed for the digestion process.

It is very important for you to know that every 50 kg person needs 5.25 grams of nitrogen per day, that is, 125 mg of nitrogen is needed for every 1 kg.

functions of nitrogen

Nitrogen gas is used to make tube lights and bulbs, and it is also used in airplane tyres, which greatly reduces the chances of a tire getting punctured. You people can also fill nitrogen gas in your vehicles which will be a bit expensive but the chances of your tyre getting punctured will be very less.

This nitrogen gas is used to make nitric acid and ammonia and it is also used to make medicines.

physical properties of nitrogen gas

  1. This gas is colorless, odorless and transparent.
  2. Nitrogen gas is lighter than air.
  3. This gas does not dissolve in water.

When nitrogen gas is reacted with calcium, it forms calcium nitrite and when magnesium is reacted with magnesium nitrite, and along with it, when nitrogen gas is reacted with hydrogen, it forms ammonia.

final conclusionFriends, today through this post of mine told you that what is nitrogen? And what does it work in our lifestyle, if you like this post, then definitely share it and if you want to get information related to studies immediately, then our telegram channel Join Jai Hind Jai Bharat.
