What is the antidote for hydrofluoric acid?
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.
Why does hydrofluoric acid cause Liquefactive necrosis?
HF progressively releases fluoride ions and the ‘free fluoride ions’ penetrate and spread into the deepest tissues, resulting in liquefactive necrosis (also known as colliquative necrosis, tissue death that liquefies the affected cells), hypocalcaemia (low calcium levels), hypomagnesaemia (low magnesium levels), and …
What does hydrogen fluoride 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.
What does HF smell like?
HF is extremely toxic and corrosive. HF can enter the body through any root of exposure. When using HF, you should not be able to smell it.
What is Liquefactive?
Liquefactive necrosis is characterized by softening of the necrotic tissue to the point at which it transforms into a pastelike mush or watery debris.
Which type of chemicals cause liquefaction necrosis?
Most bases (as well as hydrofluoric acid) cause liquefaction necrosis which turns the affected tissue to a liquid that does not stop the penetration.
What does fluoride smell like?
Fluoride occurs naturally in Earth’s crust, in rocks and minerals, and in water at varying levels. It has no taste or smell and is also present in foods such as apples, tea and almonds.
Who is the Queen of acid?
Nitric Acid (HNO3)
Nitric Acid (HNO3) is known as Queen of acids. It is fuming and corrosive. It is a powerful oxidizing agent, and reacts violently with many non-metallic compounds.
Can hydrofluoric acid dissolve a human?
Walter suggests using acid, but this has problems of its own. Walter knows that an acid such as hydrofluoric acid (HF) will be able to dissolve the bodies as it can destroy tissue and decalcify bone, so he steals a few large bottles of HF from his high school chemical stores.
