Hydrogen Chloride - ( HCL )
Hydrogen Chloride is a colorless, corrosive, toxic, nonflammable gas with a suffocating odor. It is very irritating to the mucous membranes. Hydrogen Chloride is heavier than air, fumes strongly in moist air, and has a great affinity for water. It is shipped as a liquefied gas under its own vapor pressure.
