Where Can You Buy Hydrofluoric Acid [VERIFIED]
Hydrofluoric Acid, HF, is the aqueous solution of Hydrogen Fluoride. Fluorine is the only halogen that does not form a strong acid, due in part to the electronegativity and small size of the fluorine atom which results in stronger bond formation between fluorine and hydrogen.

Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.
Most people that are looking for 100% hydrofluoric acid for sale are actually looking for 100% (or 99.9%) hydrogen fluoride. The sale of this product has been discontinued by numerous pure hydrofluoric acid and pure hydrogen fluoride suppliers including Lab Alley, which does not sell 100% hydrofluoric acid. This is an extremely hard product to located in the USA.
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.
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. It is used to make most fluorine-containing compounds; examples include the pharmaceutical fluoxetine (Prozac) and the material PTFE (Teflon). Elemental fluorine is produced from it. Solutions of HF are colorless, acidic and highly corrosive. Hydrofluoric acid is commonly used to etch glass and silicon wafers. The wafer can be immersed in a bath of etchant, which must be agitated to achieve good process control. For instance, buffered hydrofluoric acid (BHF) is used commonly to etch silicon dioxide over a silicon substrate.
Hydrofluoric acid 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. Lab Alley sells 48% Hydrofluoric Acid In Water and also 50%, 60%, 70%, 5% and 0.5%.
The only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF). While technically a weak acid, hydrofluoric acid is extremely powerful and highly corrosive. Hydrofluoric acid is a weak acid. Weak acids do not completely dissociate into their ions in water. For example, HF dissociates into the H+ and F- ions in water, but some HF remains in solution, so it is not a strong acid. There are many more weak acids than strong acids. Most organic acids are weak acids.
The Nitric Acid (15%) And Hydrofluoric Acid (1.5%) Aqueous Solution sold by Lab Alley is a clear liquid with an acidic odor. These type of mixtures are used to prepare, or etch, the surface of implantable medical devices for the application of bioactive coatings.
The principal use is in organofluorine chemistry for the production of Teflon, fluoropolymers, fluorocarbons, and refrigerants such as freon. Most high-volume inorganic fluoride compounds are prepared from hydrofluoric acid.
Hydrofluoric acid is an aqueous inorganic acid solution commonly used in research and industry for its ability to etch silicon compounds. It is an essential tool for semiconductor and electronic fabrication, mineral processing and glass etching. In addition to its useful properties, hydrofluoric acid also poses severe health risks upon exposure. Best management practices must be reviewed and continually employed while working with this material.
Hydrofluoric acid is used in chemistry, laboratory analytical work to determine silicon dioxide. Hydrofluoric acid is a catalyst, especially in the petroleum industry (paraffin alkylation); in fluorination processes, especially in the aluminum industry; in the manufacture of fluorides; for separating uranium isotopes; in making fluorine containing plastics; in dye chemistry. Hydrofluoric acid is a catalyst in alkylation, isomerization, condensation, dehydration, and polymerization reactions; fluorinating agent in organic and inorganic reactions; production of fluorine and aluminum fluoride; additive in liquid rocket propellents; refining of uranium.
Hydrofluoric acid is used for etching and glass cleaning in the manufacture of glass, semiconductors (computer chips), and ceramics (home and industrial applications). Hydrofluoric acid is used for rust removal in commercial and home laundry products. Hydrofluoric acid is used for milling titanium. Metallurgy laboratories. Hydrofluoric acid is used for petroleum exploration, refining (in alkylation units), and in the oil fields.
Hydrofluoric acid is used by dental laboratories to clean porcelain prosthetics. It is used for electroplating. It is included in some janitorial products for cleaning tiles, and ceramic devices. It is used for aluminum brighteners. It is used in various chemical industries. It is used by porcelain painters.
People who love the hit show Breaking Bad, wonder if you could really use hydrofluoric acid to dispose of a corpse, like Walter White did on the series. In season one, for instance, Pinkman poured hydrofluoric acid into a bathtub to dispose of his former business partner Emilio Koyama. The acid ate through the tub and the second floor of the home. In seasons four and five, White and Pinkman used the same method to destroy bodies.
When hydrofluoric acid comes into contact with human skin it causes deep burns. Hydrogen fluoride readily dissolves in water to form colorless hydrofluoric acid solutions; dilute solutions are visibly indistinguishable from water. Hydrofluoric Acid is extremely dangerous. If it gets on your skin, it can kill you. It is very corrosive and very toxic to humans.
Common mineral acids such as hydrochloric, phosphoric, nitric and sulfuric acid can cause surface burns when a dermal exposure occurs. The area affected is localized, in other words, only the area contacted by the acid is affected.
The mechanism for the local tissue corrosion is caused by the active hydrogen cation (H+) of the acid. Hydrofluoric acid will also cause local injuries; however, it does not stop there. The fluoride anion (F-) that dissociates from its hydrogen counterpart readily absorbs through the skin and performs its damage on the inside, penetrating deep into body tissues, causing a systemic injury.
Signs And Symptoms Of Hydrofluoric Acid ExposureSkin Exposure: Strong HF acid concentrations (over 50%) and anhydrous HF in particular, cause immediate, severe, burning pain and a whitish discoloration of the skin that usually proceeds to blister formation.The usual initial signs of a dilute solution HF burn are redness, swelling and blistering, accompanied by severe throbbing pain.
Hydrofluoric acid attacks all silica containing materials, including glass. It must be used and stored in polyethylene (PE) bottles and vessels. Bottles for storage of HF must have secure caps and lids that can provide a gas-tight seal to prevent escape of hydrogen fluoride gas. Hydrofluoric acid should never be disposed of by drain. Elementary neutralization of HF does not permit drain disposal, even if the resulting solution pH is 7. Be sure to have calcium gluconate gel and proper protective gear before responding to an HF spill.
Hydrofluoric acid (HF, CAS 7664-39-3) is a corrosive, weak, inorganic, acidic, aqueous solution of hydrogen fluoride. HF is one of the strongest inorganic acids. It is colorless, odorless, highly corrosive, and available in a range of purity grades.
Hydrofluoric acid is used in the laboratory as an intermediate in many chemical reactions and syntheses. It serves as the fluorine source for creating many organofluorine compounds, like polytetrafluoroethylene and fluoropolymers, and for high-volume inorganic fluoride compounds such as sodium aluminum hexafluoride, cryolite, and aluminum fluoride.
Hydrofluoric acid can dissolve glass, so it should be stored in polyethylene containers. Because it is extremely toxic and very dangerous, users must wear personal protective equipment. Unsafe exposure can cause local and systemic injuries and can be fatal.
Hydrofluoric (HF) acid is an extremely powerful inorganic acid and a vigorous dehydrating agent that is used in many industrial branches. Domestic concentrations of hydrofluoric acid are typically around 0.5 percent with industrial concentrations approaching 100 percent. Hydrofluoric acid is highly toxic and damaging. It penetrates into deep tissue causing liquefactive necrosis and release of cellular products. Ingestion of solutions or inhalation of fumes and vapors with unintentional and intentional exposures of hydrofluoric acid presents with dermal burns, eye injury, acute respiratory symptoms as well as causes systemic fluoride toxicity including cardiovascular, pulmonary, renal and neuromuscular symptoms, electrolyte imbalance and enzyme inhibition which can lead to cardiac arrhythmias and death.
