검증된 단계별 안내1
Identify the chemical formula given: HNO_3.
Recognize that HNO_3 is an oxyacid, meaning it contains hydrogen, oxygen, and another element (in this case, nitrogen).
Recall the naming rules for oxyacids: acids with the polyatomic ion ending in '-ate' are named with the suffix '-ic acid'.
Determine the polyatomic ion in HNO_3, which is nitrate (NO_3^-). Since the ion is nitrate, the acid name becomes 'nitric acid'.
Confirm that 'nitric acid' is the correct name, while 'nitrous acid' corresponds to HNO_2, and the other options are incorrect or not standard names.
