The equation for the dissolution of hydrogen fluoride in water can be written as:

`HF + H_2O -> H_3O^+ + F-`

We can also write the equation omitting the water in the equation  to show that HF can be ionized in the solution. We can write is as:

`HF -> H^+ + F^-`

The reason why HF can conduct electricity is because it can produce ions in the solution. Ions that are dissociated in the solution are free to move thus can conduct electricity. However, HF is not a strong acid compared to other hydrogen halides such as HCl and HBr.
