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 (W-NA) which is up to 68%
