How is Nitrogen isolated from liquid air?
Open in App
Solution
Fractional distillation of liquid air:
- Nitrogen and Oxygen gases are obtained from air.
- Liquid air consists of 78% of Nitrogen and 21% Oxygen.
- These two gases can be separated by fractional distillation of liquid air.
- In fractional distillation at low temperature, the Nitrogen becomes liquid and can then be extracted.
Conclusion: Therefore using fractional distillation liquid air produces Nitrogen.
