Characteristics of Hydrogen Chloride
Hydrogen Chloride is a colorless to slightly yellow corrosive gas with a pungent, irritating odor. Although not considered a combustible gas, it may react or form combustible compounds when contact is made with alcohol and hydrogen cyanide or with aluminum-titanium alloys. Dissolving Hydrogen chloride in water will yield a strong highly corrosive acid. It is for this reason that HCl is a strong irritant to the eyes, nose, and upper respiratory tract. Levels of 35 ppm can cause irritation to the throat even after a very short period of time.
