Toxic Substances Portal - Hydrogen Chloride

2014-10-21 · At room temperature, hydrogen chloride is a colorless to slightly yellow gas with a pungent odor. On exposure to air, the gas forms dense white vapors due to condensation with atmospheric moisture. The vapor is corrosive, and air concentrations above 5 ppm can cause irritation. Hydrogen chloride is available commercially as an anhydrous gas or as aqueous solutions (hydrochloric acid).
