Nitric Acid
built 502 days ago
Nitric Acid is a powerful oxidising agent and is widely used in the chemical industry for the nitration of organic chemicals or inorganic metals. Typical uses are in the manufacture of fertilizer, dyestuffs, explosives, fungicides & catalysts, polymer manufacture, water treatment, fibre manufacture, food processing and in the recovery of spent nuclear fuel. Its corrosive properties ... enable its use in metal pickling, metal cleaning and plating applications.

Due to the nature of Nitric Acid and its fumes the electrical and pneumatic systems are built for corrosive environments. This includes Nema 4X panels and electrical components as well as pneumatics specifically designed for this application. A containment pan for the Nitric Stage is ... included

Nitric acid is a colourless strongly fuming liquid, having a specific gravity of 1.50394 (24.2° C.) (V. Veley, Proc. Roy. Soc., 62, p. 223). It is exceedingly hygroscopic and corrosive. On distillation, the pure acid begins to boil at 78.2° C. (W.

Pure anhydrous nitric acid (100%) is a colorless liquid with a density of 1522 kg/m³ which solidifies at -42°C to form white crystals and boils at 83°C. When boiling in light, even at room temperature, there is a partial decomposition with the formation of nitrogen dioxide following the reaction:

As applies to all dangerous chemicals, if nitric acid is being transported during bad weather (for example, icy roads, snow or poor visibility) the vehicle must stop at the nearest suitable parking area. The vehicle may only continue its journey when the weather has improved. In some European countries, this is obligatory for all hazardous substances.

The nitrogen peroxide formed dissolves in the nitric acid to form the fuming acid. A little powdered starch is sometimes added to assist in the reduction of "~henitric acid. An impure fuming acid is sometimes prepared by distilling a mixture of concentrated nitric and sulphuric acids.
