Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas. It is a clear, colorless, smoky corrosive liquid with a strong irritating odor. Melting point - 83.3 C, boiling point 112.2 C, density 0.888 g/cm. It is soluble in water and ethanol and slightly soluble in ether. Because the binding ability between hydrogen atom and fluorine atom is relatively strong, the hydrofluoric acid can not be completely ionized in water, so theoretically low concentration hydrofluoric acid is a weak acid (according to its ionization constant in fact belongs to medium strong acid). It is highly corrosive and can strongly corrode metals, glass and silicon-containing objects. Inhalation of vapor or contact with skin can cause irreparable burns. Laboratories generally use fluorite (mainly composed of calcium fluoride) and concentrated sulfuric acid to make, need to be sealed in plastic bottles, and stored in a cool place.
Character: Colorless transparent solution, strong irritating odor, highly toxic, and strong corrosive. Uses: Used in chemical industry, metallurgy, glass, mining, petroleum exploitation and atomic energy industry, etc. Storage: Store in a well ventilated warehouse. Transportation: As a first-class inorganic acid corrosive substance in transportation. Packaging: It is packed in polyethylene plastic barrels or filling according to user's requirements.
