Question

explain. Is HF is the weakest acid or not.and why?​

Answer 1

$\huge \mathfrak \red{Answer:-}$

Hydrofluoric acid (HF) is a weak acid mainly because it forms stable species after it dissociates. This makes HF the only hydrohalic acid that isn't classified as a strong acid (e.g., HCl, HBr, HI).

Answer 2

Answer:

With a pKa of 3.15 HF is considered a weak acid in that it is not full disassociated below a pH of about 5.5 and will form complexes with many compounds including itself. Do not let the classification as a weak acid fool you, HF is a very aggressive and dangerous acid.

Explanation:

Means it's ph maybe a bit more, but not so weak not so strong
