Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas, clear, colorless, smoke corrosive liquid, with a severe irritating odor. A melting point of -83.3 ° C, a boiling point of 19.54, a flash point of 112.2 ° C and a density of 1.15 g cm³. Soluble in water, ethanol, slightly soluble in ether. Because hydrogen atoms and fluorine atoms are relatively strong, so hydrofluoric acid can not be completely ionized in water, so theoretically low concentration of hydrofluoric acid is a weak acid. Has a strong corrosive, can strongly corrode metal, glass and silicon-containing objects. Such as inhalation of steam or contact with the skin can cause incurable burns. Laboratory generally with fluorite (the main component of calcium fluoride) and concentrated sulfuric acid to make, need to be sealed in plastic bottles, and preserved in the shade.
