No, this is not a chemistry conference. But you come with this article may mean that you need some information on a chemical, especially nitric acid. If you can still remember your chemistry class, is the chemical formula of the substance NHO3. Perhaps you've been so busy with these formulas that could have accomplished what the substance in question and what are the applications in our laboratory society.One processes that have existed for many years of potassium nitrate with concentrated sulfuric acid and heating This process is attributed to a German chemist named Johann Rudolf Glauber. Moreover, common commercial production of nitric acid, the Ostwald process. It was a German chemist named Wilhelm Ostwald who developed the method in which ammonia gas is oxidized to nitric oxide and nitrogen dioxide by air or oxygen in the presence of a platinum catalyst gauze. Accordingly, the nitrogen absorbed from the water, allowing the formation of nitric oxide acid.Now Let's look at some of the characteristics of the substance. First, it is very corrosive, an acid is highly toxic, and this leads to emit dangerous flames. It is also a highly oxidizing substance, which reacts violently with organic materials and these reactions may be different explosive.With these properties, you may feel that a hazardous substance. Yes, it can be dangerous if not properly used and accounted for. By storing the content, make sure the storage area is cool, dry and well ventilated. It is also important to properly label the container to prevent accidents, such as ingestion of the substance. If its use is recommended to wear safety glasses, and the species that are suitable gloves when treatment with concentrations up to 70% including butyl rubber, neoprene and polyethylene.Furthermore, nitric acid is not just a matter coming to study to chemistry. Indeed, it is used in many different industries. Therefore, it is useful in agriculture, as it is used in the manufacture of fertilizers such as ammonium nitrate. As you may know, fertilizers help increase food production. Another chef used in the manufacture of explosives such as nitroglycerin and trinitrotoluene (TNT). You can also find out if the substance is mixed with hydrochloric acid, aqua regia is formed, one of the few reagents capable of solving important metals like gold and platinum? Other known uses of chemicals, the manufacture of perfumes, dyes, fungicides, and certain medications, and is also used to process spent nuclear fuels.Probably, one of his concerns with the substance or the environment and health implications. With regard to environmental considerations, the highly reactive properties of the substance to build the plant and animal tissues. It also has some effects on health when inhaled as a vapor, upon contact with skin and eyes, and whether intentionally or accidentally ingested. Inhalation of dust tends to dry throat and nasal passages, coughing, difficulty breathing, chest pain and shortness of breath. Continuous exposure to chemical agents, by contrast, can damage the lungs and the outer layer of tooth enamel or damage. Contact with skin may cause burns, blisters, sores and permanent scars. If ingested, can cause burns to mouth, throat and stomach, and even death.Thus, the health effects of nitric acid, great care must be taken when handling and use.
