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.
What does hydrofluoric acid do to the 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.
Why does hydrofluoric acid dissolve glass?
Hydrofluoric acid does indeed dissolve glass very effectively, eventually leaving nothing of it left. The way this reaction works is based on the fact that fluorine has such a high electronegativity (the ability to attract electrons). Both of these reactions dissolve the silicon dioxide (glass) in the process.
What does lime do to a dead body?
It appears they used calcium oxide — a substance more commonly known as quicklime — to to dissolve these bodies down to the bone. Rich says:. The dead animal should be covered with hydrated lime , and then covered with at least 4 feet of soil mounded up to allow for settling as the carcass decomposes [ORS 601.
Why cant acid burn through glass?
Glass is mainly SiO2, and since no element but F has the ability to dislodge oxygen from its bond, glass containers are used for all sorts of acids (HCl, H2SO4, HNO3). HF can react with glass, so it doesnt work there.
What happens if u drink acid?
Symptoms from swallowing hydrochloric acid may include: Mouth and throat burn, causing severe pain. Breathing difficulty due to swelling of throat. Severe abdominal pain.
