WebMar 22, 2024 · Hydrofluoric Acid Safety Program. What are the HF hazards? HF is a highly hazardous (corrosive) and acutely toxic. HF is unique from other chemicals because of its poisonous effects and the ability to readily absorb through the skin and attack bone. Once absorbed by the skin, HF dissociates rapidly into H + and F − ions. Toxic effects occur ... WebFluoroantimonic acid is the strongest superacid based on the measured value of its Hammett acidity function (H 0), which has been determined for various ratios of HF:SbF 5. The H 0 of HF is −15. A solution of HF containing 1 mol % of SbF 5 is −20. The H 0 is −21 for 10 mol%. For > 50 mol % SbF 5, the H 0 is between −21 and −23.
