Frequently Asked Questions

What are the hazards of hydrogen fluoride?

When heated, it emits highly corrosive fumes of fluorides. Its corrosive action on metals can result in formation of hydrogen in containers and piping to create fire hazard. Toxic and irritating vapors are generated when heated.

Why is hydrogen fluoride a weak acid?

Unlike other hydrohalic acids, such as hydrochloric acid, hydrogen fluoride is only a weak acid in dilute aqueous solution. This is in part a result of the strength of the hydrogen-fluorine bond, but also of other factors such as the tendency of HF, H 2O, and F− anions to form clusters.

Is hydrogen fluoride a strong acid?

Hydrogen fluoride is however usually found as a strong solution in water, whereby it is Hydrofluoric acid. Hydrofluoric acid is an extremely strong acid. It will severely corrode metals, glass, minerals and many organic (carbon-containing) substances - and will release highly flammable hydrogen in the process.

Why is HCl a stronger acid than HF?

HCl and HF are stronger acids than H2O because Cl- and F- are much weaker bases than OH-. Those bond energies you wrote refers only to homolitic dissociation: H-Cl --> H. + Cl. and not to ionic dissociation: H-Cl --> H+ + Cl-.
