Nitrogen is produced commercially almost exclusively from air, most commonly by the fractionaldistillation of liquid air. In this process, air is first cooled to a temperature below that of the boiling points of its major components, a temperature somewhat less than - 328°F (-200°C). The liquid air is then allowed to warm up, allowing the lower-boiling-point nitrogen to evaporate from the mixture first. Nitrogen gas escaping from the liquid air is then captured, cooled, and then liquefied once more.
This process produces a high-quality product that generally contains less than 20 parts per million of oxygen. Both an "oxygen-free" form of nitrogen (containing less than two parts per million of oxygen) and an "ultra-pure" nitrogen (containing less than 10 parts per million of argon) are also available commercially.
A number of methods are available for preparing nitrogen from its compounds in the laboratory on a small scale. For example, a hot aqueous solution of ammonium nitrite decomposes spontaneously to give elemental nitrogen and water. The heating of barium or sodium azide (NaN3 or Ba[N3]2) also yields free nitrogen. In another approach, passing ammonia gas over a hot metallic oxide will result in the formation of free nitrogen, the free metal, and water. Yet another route is the reaction between ammonia and bromine, resulting in the formation of nitrogen and ammonium bromide.

What else can I help you with?
Is N2 a pure substance or a solution?
Nitrogen (N) is a chemical element, not a solution; nitrogen can be obtained as a very pure gas.
What chemical form is nitrogen obtained by plants?
Plants typically absorb nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms are essential for plant growth and development, as they are used by plants to build proteins, nucleic acids, and other vital molecules.
Which gas is obtain by fractional distillation for industrial use?
Oxygen, nitrogen, and argon are obtained by fractional distillation for industrial use. This process involves separating air into its components based on their boiling points, with oxygen, nitrogen, and argon being the main products obtained for various industrial applications.
Where can nitrogen be found or mined at?
Elemental Nitrogen may be conveniently obtained by cryogenic distillation from the atmosphere. The liquid form is widely used as a low temperature coolant. It is an important part of our diet, and is found in proteins. Nitrates are very useful chemicals, and until recently, were obtained from immense deposits of seabird droppings, sometimes called guano.
Which material used in photosynthesis is obtained from the soil?
Mineral nutrients such as nitrogen, phosphorus, and potassium are obtained from the soil during photosynthesis. These nutrients are essential for plant growth and are absorbed through the plant's roots.
What raw material is nitrogen obtained from?
Nitrogen is obtained from the air, which is about 78% nitrogen gas (N2). It can be separated from the other gases in the air through processes such as fractional distillation or membrane separation.
What element is obtained from liquid air by fractional distillation?
Nitrogen
How is nitrogen obtained by animals?
.They get it from eating plants.
Is nitrogen a solid?
Nitrogen can be obtained as a solid at very low temperature, under -210 0C. At room temperature nitrogen is a gas.
Where is nitrogen found or obtained from?
== == Nitrogen is found in all living systems as part of the makeup of biological compounds. Nitrogen is obtained from the atmosphere by passing air over heated copper or iron. The oxygen is removed from the air, leaving nitrogen mixed with inert gases. Pure nitrogen is obtained by fractional distillation of liquid air; because liquid nitrogen has a lower boiling point than liquid oxygen, the nitrogen distills off first and can be collected.
Is N2 a pure substance or a solution?
Nitrogen (N) is a chemical element, not a solution; nitrogen can be obtained as a very pure gas.
What processes are oxygen and nitrogen obtained from the air?
Oxygen and nitrogen are obtained from air primarily through fractional distillation or liquefaction. In these processes, air is cooled and compressed to separate its components based on their boiling points. Nitrogen boils at a lower temperature than oxygen, allowing for their separation.
What gas is formed when hydrogen reacts with nitrogen?
After this reaction ammonia (NH3) is obtained.
What is the word obtained after unscrambling the word negitnor?
The anagram is nitrogen, a gaseous element.
What gas is obtained by fractional distillation?
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
What chemical form is nitrogen obtained by plants?
Plants typically absorb nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms are essential for plant growth and development, as they are used by plants to build proteins, nucleic acids, and other vital molecules.
Where is argon obtained from?
Argon is obtained by fractional distillation of liquid air, where it is separated from other gases such as nitrogen and oxygen. It is a byproduct of the production of liquid oxygen and liquid nitrogen.
