HF dissolves glass because it reacts with silicon oxide (main component of
common glass) forming soluble silicon floride. It is more dangerous
and toxic because it is not physiological (unlike HCl or H3PO4) , F ion
has a covalent radii close to one of hydrogen, yet it F is not H by any
means, and thus cellular mechanisms are disturbed. In short, fluoride ion
is rather poisonous.
