| definition |
- A toxic, colorless, strongly acidic gas (HCl) that dissolves readily in water to form hydrochloric acid.
In the troposphere, hydrochloric acid can be produced from the reaction of nitric acid or sulfuric acid with sea-salt particles (NaCl). It is also involved in the formation of ammonium chloride aerosol. HCl is also the most abundant form of chlorine in an inorganic compound found in the stratosphere.
Produced there predominantly from the reaction of Cl atoms with methane and molecular hydrogen, it acts as a temporary, relatively unreactive reservoir species for chlorine.

| Abstract from DBPedia | The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.塩化水素（えんかすいそ、英: hydrogen chloride）は塩素と水素から成るハロゲン化水素。化学式 HCl。常温常圧で無色透明、刺激臭のある気体。有毒であり、塩酸ガスとも呼ばれる。 (Source: http://dbpedia.org/resource/Hydrogen_chloride) |
