Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas, clear, colorless, fuming corrosive liquid with a pungent odor intense. Melting point -83.3 ℃, boiling point 112.2 ℃ concentrated hydrofluoric acid, density 0.988g / cm3. Soluble in water, ethanol, ether-soluble. Because ability between the hydrogen atoms and fluorine atoms bonded relatively strong hydrofluoric acid, hydrofluoric acid, so that can not be completely ionized in water, so theoretically low concentration of hydrofluoric acid is a weak acid. It is extremely corrosive and can strongly corrode metal, glass and silicon-containing objects. Toxic, such as inhalation of vapors or contact with the skin can cause burns difficult to cure. Laboratory general use fluorite (mainly composed of calcium fluoride) and concentrated sulfuric acid to make, may need to be sealed in a plastic bottle, and stored in a cool place.
