What Is Hydrogen Fluoride?
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.
Hydrogen fluoride is a highly dangerous gas, forming corrosive and penetrating hydrofluoric acid upon contact with moisture. The gas can also cause blindness by rapid destruction of the corneas.
HF is miscible with water (dissolves in any proportion). In contrast, the other hydrogen halides exhibit limiting solubilities in water. Hydrogen fluoride form a monohydrate HF.H2O (−40 °C (−40 °F), which is 44 °C (79 °F) above the melting point of pure HF. Aqueous solutions of HF are called hydrofluoric acid. When dilute, hydrofluoric acid is a weak acid, unlike the other hydrohalic acids. However concentrated solutions are strong acids.
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. It is an important feedstock in the preparation of many important compounds including pharmaceuticals and polymers (e.g. Teflon). HF is widely used in the petrochemical industry as a component of superacids. Hydrogen fluoride boils near room temperature, much higher than other hydrogen halides.
About 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 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 for cleaning cast iron, copper, brass; removing efflorescence from brick and stone, or sand particle from metallic castings; working over too heavily weighted silks; frosting, etching glass and enamel; polishing crystal glass; decomposing cellulose; enameling and galvanizing iron; increasing porosity of ceramics.
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 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.
History Of Hydrofluoric Acid
Swedish pharmaceutical chemist Carl Scheele discovered hydrofluoric acid in 1771, when he investigated the composition of a mineral called fluorspar: Calcium fluoride. At a time when the element fluorine was unknown and all acids were thought to contain oxygen, Scheele noticed the glass-etching properties of the fumes that developed when heating fluorspar in sulfuric acid. Leading the fumes into water, he was the first to make large quantities of hydrofluoric acid. The exposure to HF – along with Scheele’s bad habit of tasting and smelling the substances he discovered – might have been one of the causes for his death at the age of just 43.
Hydrofluoric Acid In Pop Culture
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.
Hydrofluoric Acid Safety And Hazards
Hydrofluoric Acid Can Cause Burns To The Skin
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.
A medical assessment in an emergency department is recommended for the following situations.
- Dermal (skin) exposure to any concentration of hydrofluoric acid where calcium gluconate gel has not been given as a first aid procedure, even if asymptomatic.
- Dermal (skin) exposure to any solution of greater than 6% hydrofluoric acid, regardless of whether calcium gluconate gel has been administered.
- Any patient developing pain, erythema, or swelling at the exposure site at any time following dermal exposure to hydrofluoric acid.
Why Hydrofluoric Acid Is So Dangerous To Use
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.
The fluoride ion has an affinity for calcium and magnesium, two minerals that are essential for bodily health. As the fluoride binds with calcium, it consumes the body’s supply of this mineral in the blood and also attacks bone structure, forming calcium fluoride salts. As serum calcium levels are depleted in the blood, a condition known as hypocalcaemia, organ failure begins to occur, heart function becomes erratic and can eventually fail, obviously resulting in death.
An additional quirk of hydrofluoric acid is that dermal burns may not be readily noticed or painful, unlike the warning properties of other acids. Skin contact with HF concentrations in the 20% to 50% range may not produce symptoms for one to eight hours. With concentrations less than 20%, the latency period may be up to twenty-four hours. A solution of only 1-2% HF exposed to greater than 10% of your body is fatal without medical attention; however dermal burns are not likely immediate.
Moderately concentrated solutions of hydrofluoric acid (>40%) tend to fume and emanate hydrogen fluoride gas when exposed to air, producing yet another exposure risk through inhalation.
Doctors treat HF poisoning with calcium gluconate injections or calcium chloride infusions to remove the fluoride ions before they devour the body’s own calcium and magnesium.
Although Hydrofluoric Acid is one of the most dangerous chemicals sold in the United States, it is industry’s main source of fluorine – pharmaceuticals, refrigerants and fluoropolymers such as Teflon all rely on hydrofluoric acid.
Signs And Symptoms Of Hydrofluoric Acid Exposure
Skin 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.
Eye Contact: HF can cause severe eye burns with destruction or opacification of the cornea. Blindness may result from severe or untreated exposures.
Inhalation: Acute symptoms of inhalation may include coughing, choking, chest tightness, chills, fever and cyanosis (blue lips and skin). All individuals suspected of having inhaled HF should seek medical attention and observation for pulmonary effects. This includes any individuals with HF exposure to the head, chest or neck areas. If there is no initial upper respiratory irritation, significant inhalation exposure can generally be ruled out.
Ingestion: If HF is ingested, severe burns to the mouth, esophagus and stomach may occur. Ingestion of even small amounts of dilute HF has resulted in death.
Safe Storage, Use, and Disposal Of Hydrofluoric Acid
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.
