";s:4:"text";s:4527:" It contains nitrogen and oxide ions. Nitrogen dioxide is very toxic. Nitrogen dioxide is used to produce rocket fuels and explosives.
Nitrogen oxides and sulfur dioxide react with substances in the atmosphere to form acid rain. It can be made by reacting concentrated nitric acid with copper or tin. Nitrogen dioxide concentration in unpolluted air is around 10 parts per billion (ppb). Sources of nitrogen dioxide pollution.
The Directive adds limit values for 27 new chemical agents, and amends 6 existing ones established by earlier directives.
It also serves as an oxidation reaction catalyst. Nitrogen dioxide is a reddish-brown gas above 21.2 °C (70.2 °F; 294.3 K) with a pungent, acrid odor, becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K), and converts to the colorless dinitrogen tetroxide (N 2 O 4) below −11.2 °C (11.8 °F; 261.9 K). Polymerization inhibitor for acrylates. In the food industry nitrogen gas is employed to prevent spoilage through oxidation, mold, or insects, and liquid nitrogen is used for freeze drying and for refrigeration systems. Although NO 2 does not poison the catalyst itself, it has a negative influence on the ionomer and the ionomer-catalyst boundaries. Nitrogen dioxide uses. Nitrogen Dioxide (NO 2) is one of a group of gases called nitrogen oxides (NO x). Here are some examples: Nitric acid manufacturing. Mining – In the mining industry, nitrogen gas is used to quickly extinguish fires by eliminating the oxygen from the air. Nitric oxide is manufactured on a large scale, and is subsequently used to make nitric acid (HNO 3 ). It finds use in the semiconductor industry for various processes. Uses of Nitrogen Oxides Although nitrogen oxides have gained dubious distinction as pollutants, they are also used beneficially in some industrial processes. Nitrogen, in the form of nitrous oxide, is also used as an anesthetic. As nitrogen dioxide, the element is vital in the industrial sector. Nitrogen dioxide is formed due to the oxidation of nitrogen oxides in the presence of oxygen. Nitrogen dioxide is a chemical compound. In one of its applications, it is used along with nitrous oxide to form oxynitride gates in CMOS devices. Room temperature sterilization agent. It is used to make nitric acid by dissolving it in water. Nitric oxide can be used for detecting surface radicals on polymers.
The nitrogen is in the +4 oxidation state. Nitrating agent in chemical explosives manufacturing. Safety .
Nitric oxide is also released. Nitrogen dioxide in the air also reacts with water vapor to form nitric acid, one of the types of acid in acid rain. It can also be made by heating some nitrates. Nitric oxide is essential to the achievement of an erection. Nitrogen oxides react with sunlight and other chemicals to form smog. Atmospheric oxidation of nitric oxide (NO) may also lead to the formation of nitrogen dioxide (1).
Another medical use of nitric oxide is in the treatment of impotence, or erectile dysfunction, in men.
Its chemical formula is NO 2. While all of these gases are harmful to human health and the environment, NO 2 is of greater concern. In the electrical industry nitrogen is used to prevent oxidation and other chemical reactions, to pressurize cable jackets, and to shield motors. Uses. Nitrogen dioxide is normally made by oxidation of nitric oxide by oxygen in air. And when an area is going to be abandoned, they use nitrogen to ensure the area will not explode.
