HF

[sarahwu3a]

Why is HF not a strong acid like HCl or HI?

[Mashkinadze_1D]

If you recall, Dr. Lavelle stated that the strength of an acid is determined by two aspects the first being how easily it gives off its H+ and the second being the stability of the remaining anion. In the case of HF, the anion would not be as stable as HCl because Cl- is able to withdraw much more e- density.

My TA said it's because F has a smaller atomic radii

but its IMF's are greater in the HF than the others due to higher electronegativity right?

F- is not stable in solution and would react with the H+ ions in solution taking them out of solution.
