Test 1 #6

Postby Elizabeth Bowen 1J » Sun Feb 02, 2020 6:17 pm

can anyone explain why percent ionization for hydrofluoric acid isn't just assumed to be 100% since HF is a strong acid?

HF, unlike the other halogen acids, is not a strong acid due to the fact that Fluoride is highly electronegative and it has a small ionic radius, meaning the HF bond is more difficult to break and therefore does not dissociate easily like the other halogen acids (HBr, HI, etc.).

HF is a weak acid and not a strong acid because it does not completely dissociate in water. The ions it forms during dissociation are too strongly bound to each other for it to be a strong acid.

It's because HF is actually a weak acid, meaning it doesn't dissociate completely!

HF is a weak acid!

HF is not a strong acid, therefore it does not completely ionize (100%)

HF is actually not a strong acid, since fluoride is so electronegative that it does not want to dissociate in water. As a result, it does not have 100% ionization.
