Why doesnt hf dissociate

It's actually the only hydrohalic acid that isn't strong. It's considered a weak acid because it doesn't completely dissociate into its ions in water. However, very concentrated solutions of HF can behave like a strong acid due to chemical bonds forming in between a base and conjugate acid.

It is more difficult for the bond to be broken, so it will not completely dissociate in water. I was assuming that HF doesn't dissociate completely because the bond between H and F is so short and thus strong. That makes it easier to generally understand the difference between strong and weak acids. Also, I didn't know that very concentrated solutions of HF can actually behave like a strong acid.

I'll definitely keep that in mind. It attacks glass, even in dilute solution, so it must be stored in plastic containers. Ultimately, the acid works its way deeper into tissues, causing bone damage and fluid buildup in the lungs. A hydrofluoric acid burn might not seem serious, but it requires immediate attention.
