Hydrogen chloride is a colourless gas with a pungent odour; its aqueous solution is known as hydrochloric acid. Hydrogen chloride is produced by burning hydrogen and chlorine together and is also a by-product of the chlorination of organic compounds. HCl is used in the production of PVC, ferric chloride and silicones.
a colorless, pungent, corrosive gas having a suffocating odor. It is heavier than air and fumes strongly in moist air. Hydrogen chloride is very soluble in water and alcohol and less soluble in ether. In semiconductor processing, hydrogen chloride is used in such processes as etching, oxidation, passivation, and epitaxy. It also is used as a plasma and reactive ion etch of silicon and polysilicon, as well as aluminum metallization.
HCl, gaseous matter, produced in fires from the decomposition of PVC, will turn into hydrochloric acid of the same formula HCl when mixed with moisture through a process called hydrolysis.
a colorless corrosive gas: HCl
chemical formula HCl, hydrogen chloride is a toxic, corrosive gas with a TLV of 5ppm. Hydrogen chloride has a pungent irritating odor and is irritating to lungs, skin and eyes. Hydrogen chloride is used as a cleaning gas during epitaxial deposition and as a furnace cleaning agent.
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.
Hydrogen chloride, also known under the name HCl, is a highly corrosive and toxic colorless gas that forms white fumes on contact with humidity. These fumes consist of hydrochloric acid which forms when hydrogen chloride dissolves in water. Hydrogen chloride gas as well as hydrochloric acid are important chemicals in chemistry, science, technology, and industry.
