Hydrosulfuric acid, also known as hydrogen sulfide or sulfane exists in the form of a colourless gas and has a rotten egg smell. Hydrofluoric acid (38%, azeotropic mixture with water) is considered as a weak acid but it is considered an important chemical reagent in wet digestion procedures due to complexing ability of fluoride ion. Hydrofluoric acid is best known to the public for its ability to dissolve glass by reacting with SiO2 (silicon dioxide), the major component of most glass, to form silicon tetrafluoride gas and hexafluorosilicic acid. Hydrofluoric acid is a highly corrosive, inorganic acid of elemental fluorine that is used in the production of plastics, semiconductors, pottery glazing, and rust removal and is a component of aluminum brighteners. View information & documentation regarding Hydrofluoric acid, including CAS, MSDS & more. Dissolving rock samples with hydrofluoric acid, the technician spilled a medium-sized beaker of 70% HF onto his lap – an area of about 10% of his body’s total surface. 0 - 100 (11) Melting Point (°C) 801 - 900 (3) 1001+ (1) Application. Let’s take a look at the chemical formula of Hydrofluoric acid. HF is commercially available in concentrations ranging from 10% to 49% with 49% HF being the most common. This is a planar molecule with one triple bond between […] Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides). Hydrofluoric acid is an aqueous inorganic acid solution commonly used in research and industry for its ability to etch silicon compounds. It is made by reacting fluorite with sulfuric acid. It has incredible corrosive abilities, most notably towards glass. Hydrofluoric acid, HF, is a fuming industrial acid of low strength. If it gets on the skin, it can kill you. Structure, properties, spectra, suppliers and links for: Hydrofluoric acid, Hydrogen fluoride, 7664-39-3, 13981-56-1, 32057-09-3. It is a very dangerous acid, being very corrosive and extremely toxic. But the more correct chemical name is "hydrogen fluoride"; "hydrofluoric acid" is only used as the name of the water solution of HF. The key difference between hydrofluoric acid and hydrochloric acid is that the hydrofluoric acid is a weak acid whereas the hydrochloric acid is a strong acid.Also, the hydrofluoric acid is capable of forming hydrogen bonds while the hydrochloric acid is unable to form hydrogen bonds.. USA; Globally; Search term: hydrofluric acid "hydrofluoric acid" Compare Products: Select up to 4 products. 83 matches found for hydrofluric acid. Hydrofluoric acid or HF is an extremely corrosive acid. Hydrofluoric Acid (HF) is a highly corrosive and toxic acid, even in a dilute form. Post SU Hydrofluoric Acid (HF) Exposure Response Instructions in labs that store or use HF solutions or gas. Ensure gel has an effective shelf life of at least one year. HYDROFLUORIC ACID attacks glass and any other silica containing material. Catalyst in alkylation, isomerization, condensation, dehydration and polymerization reactions. The chemical reactions are similar to those in the sulfuric acid process, but it is possible to use higher temperatures (between 24 and 46 °C, or 75 to 115 °F), thus avoiding the… The Hydrocyanic acid is the solution of hydrogen cyanide and water that is generally poisonous in nature and the other name for chemical substance is prussic acid. AAS (17) ICP (13) sample preparation (1) Featured Industry. May react with common metals (iron, steel) to generate flammable hydrogen gas if diluted below 65%. However, it is a weak acid and not a strong acid because it does not completely dissociate in water (which is the definition of a strong acid) or at least because the ions it forms upon dissociation are too strongly bound to each other for it to act as a strong acid. Structure . Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water. All EAS Labs which use HF are required to have a current tube of HF Antidote Gel, ie. Ensure 2.5% calcium gluconate gel (intended for dermal exposures) is available in laboratory and stored at the safety shower. Hydrofluoric acid (HF) is an extremely corrosive acid used for many purposes including mineral digestion, surface cleaning, etching, and biological staining. HF’s unique properties make it significantly more hazardous than many of the other acids used on campus. It is known for being flammable, corrosive and toxic.
