Why is oxygen colorless odorless and tasteless?

Answer 1

In high concentrations or long distances (such as our atmosphere) may be slightly perceived as bluish. Ozone is has a very strong odor, detectable by humans in concentrations as low as 0.001 ppm. However humans also can acclimate to the smell of ozone quickly, even levels that are considered dangerous for long term exposure for workplace safety, and we can not notice the smell unless we can get away from it for a while.

Answer 2

No. It has a very pungent smell. If ever after a thunderstorm you smell something like that, it is ozone. You smell this because ozone is created when lightning interacts with oxygen.

After a short period of time, your nose will become acclimated to the presence of ozone, and you will not notice it, unless the concentration increases.

Answer 3

Oxygen is colorless, odorless, and tasteless because it is a diatomic molecule with a symmetrical structure. This means that it does not absorb visible light to produce color, does not have any smell, and does not react with taste receptors in our mouths.

Answer 4

Oxygen gas has NO color, like most gases. It is also odorless.

It's the same as asking: 'What do you see and smell' when you're in (clean, fresh) air, containg 20% oxygen!

Answer 5

Gaseous, yes. Liquid oxygen is light blue.

Answer 6

Yes. xenon is colourless and odourless gas.

Answer 7

it has a dioxide content of negative zero

Answer 8

yep
