The color of oxygen depends on its state.
Oxygen's Color Spectrum
| State | Color |
|---|---|
| Gas | Colorless |
| Liquid | Pale Blue |
| Solid | Pale Blue |
Gaseous Oxygen
- As a gas, oxygen is colorless, odorless, and tasteless. This is why we can't see the air around us, which is composed of about 21% oxygen.
Liquid and Solid Oxygen
- In its liquid and solid forms, oxygen appears a pale blue. This color is due to the way light interacts with the oxygen molecules when they are more densely packed.
Additional Properties of Oxygen
* The liquid and solid states of oxygen are also strongly paramagnetic, meaning they are attracted to magnetic fields.
* These unique properties are crucial in various scientific and industrial applications.
