Nitrogen is a colorless, odorless, tasteless, nontoxic gas.
Nitrogen monoxide is colorless gas; it is also known as Nitric oxide.
There is no universally recognized color code for gas cylinders. You should always read the label rather than relying on the cylinder color. In Europe, the standard is for nitrogen cylinders to have a black shoulder, but it's still safest to read the label.
One way to detect nitrogen gas is by using a chemical nitrogen dioxide detector tube, which changes color in the presence of nitrogen dioxide gas. Additionally, nitrogen gas can be detected using a nitrogen-specific gas sensor that produces an electrical signal when nitrogen gas is present. It can also be detected by its inert properties, as nitrogen does not normally react with other substances under normal conditions.
Nitrogen gas (Nā) does not change the color of moist red litmus paper. This is because nitrogen is a neutral gas that does not have acidic or basic properties. Therefore, it will not cause any color change in the litmus paper.
Nitrogen is a colorless, odorless, and tasteless nontoxic gas.
