Description
The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colorless 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.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 .
Applications
● In the electronics industry as carrier for non-volatile elements and in selective etching
● In semiconductor fabrication: etching of native oxide prior to epitaxial deposition; CVD reactor cleaning, moisture getter in CVD oxides.
