What do you use hydrofluoric acid for?

Hydrogen fluoride is used to make refrigerants, herbicides, pharmaceuticals, high-octane gasoline, aluminum, plastics, electrical components, and fluorescent light bulbs. Sixty percent of the hydrogen fluoride used in manufacturing is for processes to make refrigerants.

Why is the HF solution colorless?

Elemental fluorine is produced from it. It is commonly used to etch glass and silicon wafers. When hydrofluoric acid comes into contact with human skin, it causes deep burns….Hydrofluoric acid.

What do they dissolve bodies with in breaking bad?

hydrofluoric acid (HF)
In a gruesome scene, Jesse adds hydrofluoric acid (HF) to dissolve the body. It’s a useful acid to have in any lab because of its unusual chemistry. It dissolves glass and so has to be stored in plastic (PTFE or Teflon) bottles.

Is hydrofluoric acid soluble in water?

Hydrogen fluoride readily dissolves in water and is referred to as hydrofluoric acid (HFA) in its dissolved form. It is present in a variety of over-the-counter products at concentrations of 6–12%.

Is hydrofluoric acid in car batteries?

Hydrofluoric acid: the chemical hazard hiding in electric and hybrid vehicle batteries. These batteries offer high energy density in comparison to the relative weight, they can store several hours of electricity and they can be quickly and easily recharged.

Can hydrofluoric acid dissolve humans?

Hydrofluoric acid is very nasty stuff, but it isn’t a strong acid. Even when dilute it will etch glass and ceramics, but it won’t dissolve or burn flesh.

Why is HF so corrosive?

Fluorine forms VERY strong covalent bonds, and it forms them very readily. HF destroys you because very small molecules can penetrate deeply, and HF is small and fluorine can replace OH in most molecules and having replaced OH it stays put. Hydroxyl groups are key parts of the molecules of life.

Does HF dissolve bone?

Hydrofluoric acid (HF) differs from other acids because the fluoride ion readily penetrates the skin, causing destruction of deep tissue layers, including bone.

Is the chemistry in breaking bad accurate?

Originally Answered: How accurate is the chemistry on “Breaking Bad”? Some is good, some is bad. The fake meth/mercury fulminate is Hollywood. Mercury fulminate is a shock sensitive explosive, but mercury fulminate doesn’t form crystals like that and is far too unstable to be carried the way he does.

How smart is Walter White?

“What would be a good estimate of Walter White’s IQ”? 145 is a good estimate of Walter White’s IQ. That’s just above genius level, which is 140. Somebody with an IQ of 145 is very capable of being a college professor or a chemist.

How do you dilute HF?

Very small amounts of 2% HF may be disposed by diluting with cold water, then flushing down the drain with plenty of cold water. Rinse beakers thoroughly with water when finished.

Is HF AQ an acid or base?

In the reaction F-(aq) + H2O(l) K HF(aq) + OH-(aq), F- is the base and H2O is the acid in the forward reaction, and HF is the acid and OH- is the base in the backward reaction.

What is hydrofluoric acid?

Hydrofluoric acid. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. It is a precursor to almost all fluorine compounds, including pharmaceuticals such as fluoxetine (Prozac), diverse materials such as PTFE (Teflon), and elemental fluorine itself. It is a colourless solution that is highly corrosive,…

What is the antidote for hydrofluoric acid toxicity?

ANTIDOTE: There is no antidote for hydrofluoric acid (HF) toxicity. Calcium – or magnesium -containing antacids (which bind fluoride ion) have been suggested for use in the treatment of ingestion exposure. Quaternary ammonium compounds or calcium -containing gels may be used topically in the treatment of skin burns.

How do you make hydrofluoric acid?

Hydrofluoric acid was first prepared in 1771, by Carl Wilhelm Scheele . It is now mainly produced by treatment of the mineral fluorite, CaF 2, with concentrated sulfuric acid at ca. 265 °C. CaF 2 + H 2 SO 4 → 2 HF + CaSO 4. The acid is also a by-product of the production of phosphoric acid from apatite / fluoroapatite.

What is hydrofluoric acid used for in dentistry?

A 5% to 9% hydrofluoric acid gel is also commonly used to etch all ceramic dental restorations to improve bonding. For similar reasons, dilute hydrofluoric acid is a component of household rust stain remover, in car washes in “wheel cleaner” compounds, in ceramic and fabric rust inhibitors, and in water spot removers.
