Hydrogen Chloride (HCl)
DESCRIPTION (Hydrogen Chloride):


Anhydrous Hydrogen Choloride is a colorless, pungent, corrosive gas having suffocating odor. Hydrogen Chloride is heavier than air and fumes strongly in moist air. It is very soluable in water, alcohol, and ether. Typically used in the production of vinyl, cotton, and for etching semi-conductor crystals.
