When we breathe in air, about 78% of it is nitrogen. Our bodies do not use this nitrogen, so when we exhale, the nitrogen is released back into the atmosphere unchanged.

Is nitrogen in the air harmful?

Nitrogen in the air is not harmful to humans at normal concentrations. In fact, nitrogen makes up about 78% of Earth's atmosphere and is essential for life. However, inhaling pure nitrogen in high concentrations can cause asphyxiation by displacing oxygen in the air.


What colorless odorless tasteless gas that you breathe in?

Oxygen (O2) from the atmosphere. However we also breath in (inhale) nitrogen. but nitrogen does not have any known effect on humans , and so in exhales also as nitrogen. We also breath in traces of other gases, such as the noble (inert) gases except Carbon dioxide. We exhale (breath out) carbon dioxide. Carbon dioxide is required in the lungs to maintain a breathing rate. If no CO2 was present in the lungs we would probably pant, or breath in an uncontrolable way.


Why human not die breathing mostly nitrogen in atmosphere?

Humans breathe a mixture of gases in air, not just nitrogen. Nitrogen itself is not harmful to humans in normal concentrations found in the atmosphere. However, breathing pure nitrogen can displace oxygen in the lungs and lead to asphyxiation.


Why nitrogen is used as disinfectant?

Nitrogen is not commonly used as a disinfectant. Disinfectants are typically chemical solutions or agents that are specifically designed to kill or inactivate microorganisms. Nitrogen is an inert gas and does not possess disinfectant properties.


Is the air we breath is mostly nitrogen?

Yes, the air we breathe is mostly nitrogen, with about 78% of the atmosphere made up of nitrogen. Oxygen makes up about 21% of the air, with trace amounts of other gases such as carbon dioxide, argon, and others.
