Solution

The correct option is A True
Yes, Nitrogen can be considered the solvent for the rest of the gases in the atmosphere.
The concept is simple.
First we need to recognize if it is a solution. Then decide which component is in the highest quantity. That by definition is the solvent.
In this case, air is a solution because it is homogeneous and single phase. Nitrogen is present in the highest quantity, so it is the solvent.

Q. (a) Explain how, nitrogen , oxygen and argon gases are separated from air.
(b) Draw a flow diagram of the processes involved in obtaining gases like nitrogen, oxygen and argon from air.

Q. _______ of air is used to obtain nitrogen, oxygen, and argon and other atmospheric noble gases by separating the air components by fractional distillation in a cryogenic air separation unit.

Fractional distillation is the separation of a mixture into its component or fractions. This process is based on difference in boiling point of the components in the mixture. This is a special type of distillation.

Air is a homogeneous mixture of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases such as helium, krypton, nitrogen dioxide etc.

Consider three gases oxygen, nitrogen and argon whose boiling points are: -183, -196, -186 degree celsius. They are to be separated from air using fractional distillation.

Air is compressed by increasing pressure and is then cooled by decreasing the temperature to form liquid air. This liquid air is allowed to warm-up slowly in a fractional distillation column, where gases get separated at different heights depending upon their boiling points. As the height of tower increases the temperature increases.

Among the three gases, which gas is collected at last?
