What are the properties of nitrogen gas ?

Nitrogen gas properties

Nitrogen gas ( N2 ) is mainly found in the atmosphere , it is also found in the Earth’s crust in the form of nitrates , it is found in the organic form in the living or dead plants and the organisms which form the humus .

Nitrogen gas is a colorless, odorless and tasteless gas that makes up 78 % of the atmosphere volume , it does not help in burning , it is nonflammable and it will not support combustion .

Nitrogen gas scarcely dissolves in the water , it is slightly lighter than air and slightly soluble in water , and it condenses at its boiling point -195.8o C (-320.4o F ) to a colorless liquid that is lighter than the  water .

Nitrogen compounds are formed naturally through the biological activity , they are also formed at high temperature or at moderate temperature with the aid of catalysts , it will combine with active metals such as lithium , magnesium and titanium to form nitrides at high temperatures  .

Nitrogen gas is necessary for many biological processes , and is used as a fertilizer in the form of ammonia or ammonia-based compounds , and the compounds formed with halogens and certain organic compounds can be explosive .

Nitrogen gas is not an inert gas , it forms nitric oxide and nitrogen dioxide with oxygen , ammonia with hydrogen , and nitrogen sulfide with sulfur .

Nitrogen gas is used in industry such as the petroleum processing , the  chemicals , the pharmaceuticals , the glass , and the fabrication processes , the steelmaking and other metals refining , the pulp , the paper manufacture , and it is used in the healthcare .

Nitrogen gas may be referred to as LIN or LN in its liquid form , and GAN or GN in its gaseous form , Gaseous nitrogen is valued for inertness ,  and it is used to shield potentially reactive materials from contact with oxygen .

Nitrogen gas does not easily react with a lot of elements as it is inactive element ,  it has a neutral effect on litmus paper , and it can be condensed into a liquified state .

When liquid nitrogen is vaporized and warmed to ambient temperature , it absorbs a large quantity of heat , and the combination of inertness and its intensely cold initial state makes liquid nitrogen an ideal coolant for certain applications such as the food freezing .

Liquid nitrogen is  used to cool the materials which are heat sensitive or normally soft to allow machining or fracturing , such as the  tires , the plastics , some metals and the  pharmaceuticals , so liquid nitrogen is valued for coldness as well as inertness .

Nitrogen gas combines with lighted magnesium ribbon forming a white substance that reacts with the water forming ammonia gas which has a pungent smell .

Nitrogen gas is produced in large volumes in both gas and liquid form by cryogenic distillation , and cryogenic processes can produce very pure nitrogen .
