What are the properties and composition of nitrogen gas?
Pure nitrogen is a liquefied gas. When in molecular form, it is colorless and nitrogen only reacts chemically with lithium at room temperature.
Chemical properties: Nitrogen is a nonmetal with electronegativity at 3.04, with 5 electrons in the outermost layer. Thus, it is trivalent in most compounds.
Nitrogen liquefies at 77°K (-196°C) at atmospheric pressure and freezes at 63°K (-210°C). Liquid nitrogen is a refrigerant commonly used in daily-life.
Physical properties: Nitrogen is slightly soluble in water, easily liquefied and solidified at low temperatures. This gas does not sustain burning and respiration.
How to make up nitrogen?
The demand for nitrogen gas is increasing rapidly, then have you ever wondered how nitrogen gas is prepared or produced?
In industry, nitrogen gas is produced in large quantities by liquid-air fractional distillation based on the principle that substances in air are boiling differently. And then, people collect nitrogen gas after the reaction by water repulsion method.
In the laboratory, nitrogen gas is made up by using nitrite salt pyrolysis through the chemical reactions below:
What is the nitrogen supply method?
