Why is HCl a strong acid but not HF? Is it because of the electronegativity of Flourine?
The reduced acidity of
The acid base reaction of the hydrogen halides in water is so represented:
What studies there are of gas phase acidities (which is a different concept to these aqueous acidities and which removes solvation) suggest that the acidities of the hydrogen halides are roughly comparable. Thus solvation seems to operate in the case of hydrogen fluoride acidities.
