Can nitric acid kill you?
(2) Nitric acid (HNO3) is highly corrosive. If inhaled, it irritates and burns the lungs and throat badly, potentially leading to pulmonary edema and death. If it's swallowed, it burns through the lining of the throat and stomach. Finally, note that breathing nitrogen can kill you too!
