Nitric Acid
Strong Inorganic Acid
Nitric Acid is a highly corrosive, strong inorganic acid with the chemical formula HNO₃. It is typically a colorless to pale yellow liquid with a sharp, suffocating odor.
Nitric acid is widely used in fertilizer manufacturing, explosives, metal processing, chemical synthesis, and laboratory applications. It is valued for its strong oxidizing properties and high reactivity in industrial processes.

Nitric Acid Applications
Nitric acid is widely used in chemical manufacturing as a strong oxidizing agent and nitrating agent. It is essential for the production of nitrates, nitro compounds, and chemical intermediates.
Nitric acid is used in the electronics industry for etching, cleaning, and refining processes in semiconductor and circuit board manufacturing.
Nitric acid is a key raw material in the manufacture of nitrogen-based fertilizers such as ammonium nitrate, supporting agricultural productivity and crop growth.
In pharmaceuticals, nitric acid is used in the synthesis of active pharmaceutical ingredients (APIs), intermediates, and laboratory-scale chemical reactions.
It is used in the production of explosives and blasting agents through nitration processes, including the manufacture of nitroglycerin and TNT under controlled conditions.
Nitric acid is applied in water treatment systems for pH control, cleaning of membranes, and regeneration of ion exchange resins.
In metal processing, nitric acid is used for pickling, passivation, and surface treatment of stainless steel and other metals to improve corrosion resistance.
It is commonly used in laboratories as a strong acid reagent for chemical analysis, sample digestion, and research applications.
