Magnesium Reacting with Nitric Acid

Mg + 2HNO3 → Mg(NO3)2 + H2

نظرة عامة

Magnesium reacts with dilute nitric acid to produce magnesium nitrate and hydrogen gas. With concentrated HNO3, nitrogen oxides form instead of hydrogen because nitric acid is an oxidizing acid. This reaction demonstrates the dual nature of nitric acid as both an acid and oxidizer.
