Question

How do you separate nitrogen from air?

Answer 1

1. Air may be divided into its components into special units by means of distillation.
2. In order to obtain high-purity nitrogen$\left({\mathrm{N}}_2\right)$, oxygen$\left({\mathrm{O}}_2\right)$ and argon $\left(\mathrm{Ar}\right)$ in liquid and gaseous form, so-called air fractionating plants use a thermal method known as cryogenic rectification to isolate the individual components from each other.
3. The atmosphere of the Planet is $78$ percent nitrogen gas, or ${\mathrm{N}}_2$.
4. While there’s so much nitrogen in the air, there’s very little nitrogen in the crust of the Earth.
5. Any very rare minerals, such as saltpetre, can be found in it.
6. In all living species on Earth, including plants and animals, nitrogen can also be present.
