Explanation:

Separation Techniques: Obtaining Gases from Air

We know that air is a homogeneous mixture of gases. It consists of gases like nitrogen, oxygen, carbon dioxide, argon, etc. in different proportion. Since it is a homogeneous mixture, we need special separation techniques. Fractional distillation is the technique that is used for obtaining different components from the air.
