Nitric oxide is an inorganic compound with the chemical formula NO. It is a nitrogen oxide compound with a nitrogen valence of +2. It is a colorless gas at room temperature and pressure, slightly soluble in water, soluble in ethanol and carbon disulfide. Nitrogen dioxide, with the chemical formula NO2, is a brown-red gas. At room temperature (0~21.5℃), nitrogen dioxide coexists with nitrogen tetroxide. It is toxic and irritating. It dissolves in concentrated nitric acid to form fuming nitric acid. It can be superimposed to form nitrogen tetroxide. It reacts with water to form nitric acid and nitric oxide. It reacts with alkali to form nitrates. It can react violently with many organic compounds.
