- In its gas form, nitrogen is colorless, odorless and generally considered as inert. In its liquid form, nitrogen is also colorless and odorless, and looks similar to water, according to Los Alamos.
- Nitrogen (N2) solubility at 20oC and pressure = 1 bar is approximately 20 mg/L. Nitrogen solubility may differ between compounds. Nitrogen (I) oxide solubility is 12 g/L, and nitriloacetate (salt) solubility is 640 g/L, whereas nitrogen chloride is water insoluble. Nitrates and ammonia dissolve in water readily.
