Uses of Nitric Acid:

• Fertilizer Production: Used to produce ammonium nitrate, a major component of fertilizers.
• Explosive Production: Used in the production of explosives like TNT and nitroglycerin.
• Industrial Processes: Used in metal etching, refining, and cleaning.
• Laboratory Reagent: Used in various chemical reactions and analytical procedures.
