WebMar 3, 2004 · Oddly enough, it's not that strong an acid in the traditional sense. The fluorine doesn't want to let go of the proton enough. It's strong enough to burn, but the big problem is how penetrating it is. As soon as it hits anything moist - like your lungs - it dissolves in the water and turns into hydrofluoric acid again. WebHydrofluoric acid etches glass, due to the strong bond formed between fluoride anions and the silicon molecules in glass. HF will also react with glazes, enamels, pottery, concrete, rubber, leather, many metals (especially cast iron) and many organic compounds. Hydrogen gas, which may pose an explosion hazard, is generated upon reaction with ...
