Product Description

  Hydro fluoric acid. It is an aqueous solution of hydro gen fluoride gas, a clear, colorless, fuming corrosive liquid with a strong irritating odor. Hydro fluoric acid is a weak acid that is extremely corrosive and can strongly corrode metals, glass and silicon-containing objects. Inhalation of vapors or contact with skin can cause incurable burns. The laboratory generally uses fluorite (the main component is calcium fluoride) and concentrated sulfuric acid to prepare, which needs to be sealed in plastic bottles and stored in a cool place.
