Identify the chemical formula given: HF.
Recognize that HF is a binary acid composed of hydrogen and a halogen (fluorine).
Recall the naming convention for binary acids: use the prefix 'hydro-', then the root of the halogen name, and end with the suffix '-ic acid'.
Apply this rule to HF: the halogen is fluorine, so the root is 'fluor-', and adding the suffix '-ic acid' gives 'hydrofluoric acid'.
Confirm that 'hydrofluoric acid' is the correct systematic name for HF, rather than other options like 'fluoric acid' or 'fluorine acid'.
