FAQ

Why doesn’t hydrofluoric acid dissolve plastic?

Why does hydrofluoric acid not dissolve plastic?

Hydrofluoric acid won’t eat through plastic. It will, however, dissolve metal, rock, glass, ceramic. Hydrofluoric acid is so corrosive because the fluorine ion is highly reactive. Even so, it is not considered a ‘strong’ acid because it does not completely dissociate in water.

Can hydrochloric acid burn through plastic?

Plastics generally do not react with acids, and the plastics that are used with acid storage are especially unreactive. Glass also does not react with HCl. Metals and other materials, on the other hand, do react readily with the acid. This is why they are not commonly used to store this acid.

Can you actually dissolve a body in hydrofluoric acid?

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. Concentrated alkalis such as Sodium Hydroxide are readily available and are very good at dissolving flesh (which is why they are commonly used as drain cleaners).

Why is HF stored in plastic?

Hydrogen fluoride(HF) ion is stored in plastic bottles because of its high reactivity towards glass and moderate reactivity towards many metals.

What is the most dangerous acid?

Hydrofluoric Acid

Even so, it’s probably the most dangerous acid in this list because it’s the one you’re most likely to encounter. This acid is used to make fluorine-containing drugs, including Teflon and fluorine gas.

How much hydrofluoric acid will kill you?

A splash of HF to more than 25% of the body can be fatal. mucous membranes begins at 5 ppm. If you can smell it, chances are the concentration is too high and immediate steps must be taken to lower it. Fluoride ions migrate through the body destroying tissue until lodging in the bones.

What plastic is safe for hydrochloric acid?

Storing Hydrochloric Acid

Metal containers are not suitable storage containers for hydrochloric acid due to its corrosive nature. Plastic containers, such as those made of PVC, can typically be used to store hydrochloric acid.

Does acid destroy plastic?

Polypropylene and polyethylene are resistant to conventional acids but can be dissolved by super acids. The main reason plastics are resistant to acids is that they are nonpolar materials like oil. This means that it takes a super acid to ionize the atoms to pull it into solution in water.

Does stomach acid dissolve plastic?

Your stomach’s primary digestive juice, hydrochloric acid, can dissolve metal, but plastic toys that go down the hatch will come out the other end as good as new. (A choking hazard is still a choking hazard, though.)

Does acid destroy DNA?

Unlikely. DNA degrades rapidly in low pH and high heat, both of which are produced in a body decomposed by sulfuric acid.

Can you dissolve a body in a bathtub?

Dissolving a Body in Lye

If the lye mixture is heated to boiling, tissue can be dissolved in a matter of hours. Lye is used to remove clogs in drains, so it could have been poured into a bathtub and rinsed away, plus it is much more readily available than hydrofluoric acid.

What do they dissolve bodies with in breaking bad?

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.

Why is HF so dangerous?

HF penetrates tissue more quickly than typical acids. Because of this ability, systemic toxicity can occur by dermal, ocular, inhalation and oral routes. When human tissue is exposed to concentrated HF, the molecules disassociate into individual hydrogen and fluoride ions. The hydrogen ion burns like any other acid.

What does HF do to your body?

Breathing hydrogen fluoride can damage lung tissue and cause swelling and fluid accumulation in the lungs (pulmonary edema). Skin contact with hydrogen fluoride may cause severe burns that develop after several hours and form skin ulcers.

How do you neutralize HF?

You can neutralize small spills (100 mL or less) by covering with magnesium sulfate (dry) and absorbing with spill control pads or other absorbent materials. Add sodium bicarbonate or magnesium oxide to any absorbent and place in a plastic container for disposal. Wash the spill site with a sodium bicarbonate solution.
