Industrial & Laboratory Chemical
Nitric Acid is a widely used industrial chemical supplied by ARASCO Conster Action Limited to customers in fertilizer production, metal processing, chemical manufacturing, and laboratory applications.
Nitric Acid (chemical formula HNO₃, CAS No. 7697-37-2) is a highly corrosive, strong mineral acid and powerful oxidizing agent, produced industrially through the catalytic oxidation of ammonia (the Ostwald process). In its pure state, it is colorless, though commercial samples often carry a pale yellow tint. Most commercially traded Nitric Acid is supplied at 60–68% concentration in water.
