Nitric Acid, with the chemical formula HNO3, is a highly corrosive and strong mineral acid. It is a colorless to yellowish liquid that emits pungent fumes and is known for its powerful oxidizing properties. Nitric acid is a vital chemical in various industrial and laboratory applications. One of its primary uses is in the production of fertilizers, where it is employed to make ammonium nitrate, a key component in many types of fertilizers.

Nitric acid is also utilized in the manufacturing of explosives, particularly nitroglycerin, which is a critical component in dynamite. It plays a crucial role in the etching of metals, making it valuable in the electronics and semiconductor industries. In laboratories, nitric acid is used as a reagent in chemical analysis and for dissolving various metals, including gold and platinum. Its oxidizing nature makes it a versatile chemical for a wide range of applications, including rocket propulsion, metal refining, and the production of nitrate salts.
