Hydrofluoric acid hydrogen ions on human tissue dehydration and corrosion, and fluorine is one of the most active non-metallic elements, combined with the hydrogen ions than the prison (ionization constant K = 3.5 × 10 ^ 4).

Hydrofluoric acid on the skin has a strong corrosive, strong penetration, and tissue protein dehydration and dissolution. After contact with skin, HF status of a non-ionic dissociation constant penetration into the deeper tissues, dissolving the cell membrane, resulting in the epidermis, dermis, subcutaneous tissue, muscle and even liquefaction necrosis, the formation of difficult healing ulcers.

While the acid’s body-dissolving effects were grossly exaggerated in the TV series, hydrofluoric acid, or HF, does indeed need to be stored and used in plastic containers as it slowly dissolves many materials, including the fibreglass many modern bathtubs are made of. HF slowly dissolves silicon dioxide – the major component of most types of glass – by forming water-soluble hexafluorosilicic acid and gaseous silicon tetrafluoride. Chemists use the acid’s ability to etch glass for removing particularly stubborn stains from laboratory glassware and it is an invaluable tool in the semiconductor industry for cleaning silicon wafers.
