Answer: Hydrofluoric acid or HF is an extremely corrosive acid. However, it is a weak acid and not a strong acid because it does not completely dissociate in water (which is the definition of a strong acid) or at least because the ions it forms upon dissociation are too strongly bound to each other for it to act as a strong acid. Why Hydrofluoric Acid is a Weak Acid. Hydrofluoric acid is the only hydrohalic acid (e.g., HCl, HI) that is not a strong acid. Hydrogen fluoride does actually dissolve fairly freely in water, but the H3O+ and F- ions are strongly attracted to each other and form the strongly bound pair, H3O+ Â· F-.
