Hydrofluoric Acid Formula

Learning the hydrofluoric acid formula is crucial for students as this acid is one of the most common acids used in many industrial processes. This acid is also widely used in the preparation of many useful fluorine compounds. It is an inorganic acid which is colourless and highly corrosive capable of dissolving many substances and compounds like oxides.

However, the acidity of the hydrofluoric acid mainly depends on the hydrogen-bond interactions of the fluoride ion. In a gaseous state, it is a highly poisonous gas.

Hydrofluoric Acid Chemical Formula

The chemical formula of hydrofluoric acid is given as HF. The acid consists of a diatomic molecule with strong intermolecular hydrogen bonds. The chains in the molecules are usually shorter and exist between five to six molecules on an average.
