About Nitric Acid 70% Solution, ACS Reagent Grade

Nitric Acid (HNO3) is a highly corrosive and strong mineral acid and it is distinguished by its potent antioxidant property. Like other Nitric Acid percentages of concentration, in its pure form appears colorless but, over time, tends to acquire a yellow cast due to the decomposition of the nitrate; it has a sour odor.

Nitric acid is commonly used in various industrial and laboratory applications due to its strong oxidizing properties. 

  • Chemical Manufacturing: Nitric acid is a key ingredient in the production of fertilizers, explosives (such as dynamite), and various organic and inorganic nitrogen compounds.

  • Metal Processing: It is used in metal etching, metal cleaning, and metal polishing processes. Nitric acid can remove oxide layers from metals, making it useful in surface treatment and preparation.

  • Laboratory Applications: It is commonly employed in laboratory settings for analytical chemistry, where it is used as a reagent or solvent for various experiments and reactions.

  • Cleaning and Passivation: Nitric acid can be used to clean and passivate stainless steel and other metals, removing contaminants and creating a protective oxide layer on the surface.

  • Reducing agent
  • Oxidizing agent
