Nitric acid is found in nature, and it can be synthetically produced in a laboratory. Free nitric acid is found in rainwater. It's also an ingredient in fertilizers, explosives such as nitroglycerin and TNT, dyes, plastics, rocket propellants and cleaning solutions. In the laboratory, nitric acid is made by distilling nitrates and sulfuric acid.Know More
According to Encyclopedia.com. nitric acid is a colorless or pale liquid that is highly corrosive and poisonous. One of the strongest mineral acids, nitric acid is a strong oxidizing agent that readily ionizes in solution and conducts electricity well. The substance reacts with metals, oxides and hydroxides to form nitrate salts.
Commercially available forms of nitric acid usually contain 52 to 68 percent nitric acid in water. In solution concentrations of 86 percent or more, nitric acid is called fuming nitric acid. Two types of fuming nitric acid exist: white fuming nitric acid and red fuming nitric acid. Treating either form yields inhibited fuming nitric acid, which is more resistant to corrosion in metals.
Nitric acid causes burns when it comes in contact with the skin. Swallowing it causes burns to the mouth and ulceration to the throat. Relief occurs when an alkaline solution is administered as treatment.Learn more about Acids & Bases
Fuming nitric acid is a pale-yellow to reddish-brown liquid that generates red-brown fumes. It is toxic to inhale, corrosive to metals and tissue, and both prolonged exposure to low concentrations or short exposure to high concentrations can result in adverse health effects.Full Answer >
The Lewis structure of nitric acid has a nitrogen atom at the center surrounded by three oxygen atoms, one of which joins to a hydrogen atom. The structure has one double bond between nitrogen and one of the hydrogen-free oxygen atoms.Full Answer >
According to Deborah Spurlock of Indiana University Southeast, "the yellow stains on skin caused by nitric acid are the result of a xanthoprotein reaction." Xanthoproteic acid forms when nitric acid reacts with amino acids on the skin, and this reaction produces the yellow tint. Corrosion Doctors state that nitric acid is considered to be a strong acid and oxidant that is aggressive to most metals.Full Answer >
Hydrocyanic acid, also known as prussic acid, is found in the pits of fruit such as apricots, peaches, nectarines, bitter almonds and cherries. Car exhaust, and the smoke from wood, tobacco and certain plastics also release amounts of prussic acid.Full Answer >
