What is HF gas?
Hydrogen fluoride is a chemical compound that contains fluorine. It can exist as a colorless gas or as a fuming liquid, or it can be dissolved in water. When hydrogen fluoride is dissolved in water, it may be called hydrofluoric acid.
Is HF a gas or aqueous?
Hydrogen fluoride is a chemical compound with the chemical formula HF. This colorless gas or liquid is the principal industrial source of fluorine, often as an aqueous solution called hydrofluoric acid….Hydrogen fluoride.

How do you make HF gas?
Anhydrous hydrogen fluoride (HF) is an inorganic, corrosive compound with many industrial and commercial uses. It is manufactured by heating purified fluorspar (calcium fluoride) with concentrated sulfuric acid to produce the gas, which is then condensed by cooling or dissolving in water.
What does HF gas smell like?
Hydrofluoric Acid: What Does it Smell Like The smell of the acid is a strong, irritating odor that will be followed by symptoms of severe injury to the skin and eyes, inhalation and ingestion irritation.
What is the use of HF?
Industrial/Manufacturing Uses Hydrogen fluoride is used to make refrigerants, herbicides, pharmaceuticals, gasoline, stainless steel kitchen products, aluminum, plastics, electrical components and incandescent light bulbs (electric light with a wire filament, used in appliances, incubators, portable lighting).
Why is HF liquid?
As there is hydrogen bonding in case of HF so it is liquid whereas HCl is gas as there is lack of hydrogen bonding in HCl. Was this answer helpful?
Is HF aqueous?
The Technical Info: Hydrofluoric acid (CAS#7664-39-3) is the aqueous form of hydrogen fluoride gas, miscible with water. Both versions are commonly referred to as HF in research and industry. It has a molecular weight of 20.01 and can typically be found in concentrations of 48-52% in water.
Is hydrofluoric acid legal?
In spite of the legal authority present to enact a ban on hydrofluoric acid paired with the dangerous propensities of the substance, the EPA has chosen to continue to allow its use in oil refineries.
Why is HF fatal?
Severe health effects or death will result from depletion of calcium from blood and tissues. Chronic exposure to low level of HF vapor may irritate respiratory system and cause problem to the bones. Even brief exposure to high levels of the vapor may cause severe damage to the respiratory system.
Is HF flammable?
UN 1052, anhydrous hydrogen (HF), may burn, but it does not ignite readily. Fire will produce irritating, corrosive, and/or toxic gases.
