Nitric Acid | Yara International

Nitric Acid is a clear, yellow liquid with a strong odor. To produce it, we start with ammonia, which is also produced in our own plants. The ammonia is oxidized on platinum webs, producing nitrous gases such as NO 2. These gases are then absorbed in water. From this, we get weak Nitric Acid (WNA) which is up to 68% (azeotrope). Through a rectification process we increase the concertation up

Citric Acid vs. Nitric Acid Passivation

10.01.· A. Passivation in nitric acid or citric acid cause acid penetration into deep hard to reach pores. Even with thorough rinsing you cannot remove all acid from such pores. These pores are the origin of local surface corrosion, while other area is passive. We suggest to rinse metal parts after passivation in diluted alkali solution. As an example of such solution: Na2HPO4 + NaNO3 with pH 89
