The question of whether hydrofluoric acid is completely ionized
The ionization of husband acid has been discussed in the academic community. Hydrofluoric acid ($HF $) is also a weak acid, and it is not completely ionized in water.

Because the chemical bond between hydrogen atom and fluorine atom is very strong, although the action of water can cause it to be partially ionized, it is difficult to achieve complete state. When hydrofluoric acid is dissolved in water, some of the $HF $molecules dissociate into hydrogen ions ($H ^ + $) and fluorine ions ($F ^ - $), while a large number of $HF $molecules remain intact.

The experimental data, at a certain temperature and concentration, measure the pH of hydrofluoric acid solution, and it can be seen that the concentration of hydrogen ions is lower than that of theoretical complete ionization. Furthermore, it can also be proved that hydrofluoric acid is only partially ionized by measuring conductivity and other methods.

In summary, it can be seen that hydrofluoric acid is not completely ionized.
