Answer
Oxygen is primarily produced industrially through the fractional distillation of liquid air.
Step-by-step solution
4 stepsAir is compressed and cooled to liquefy it.
The liquid air is then fed into a distillation column.
Nitrogen, which has a lower boiling point (-196°C), vaporizes first and is removed.
Liquid oxygen, with a higher boiling point (-183°C), remains at the bottom of the column and is collected.
Another method is electrolysis of water, where water (H₂O) is split into hydrogen (H₂) and oxygen (O₂) using an electric current.
2H₂O(l) → 2H₂(g) + O₂(g)
