Verified step by step guidance1
Identify the chemical formula given: HF.
Recognize that HF is a binary acid composed of hydrogen (H) and a halogen (fluorine, F).
Recall the naming convention for binary acids: use the prefix 'hydro-', then the root of the nonmetal element, and end with the suffix '-ic acid'.
Apply this rule to fluorine: the root is 'fluor-', so the acid name becomes 'hydrofluoric acid'.
Confirm that 'hydrofluoric acid' is the correct systematic name for HF, distinguishing it from other options that do not follow the standard naming conventions.
