What is the use of nitric oxide?

Nitric oxide is a gas that is inhaled. It works by relaxing smooth muscle to widen (dilate) blood vessels, especially in the lungs. Nitric oxide is used together with a breathing machine (ventilator) to treat respiratory failure in premature babies.
A.

How do you get nitric acid?

Chemically, nitric acid is made by bubbling nitrogen dioxide into water. So the objective in this approach is to generate nitrogen dioxide. This can be done by reacting hydrochloric acid, a nitrate salt and copper.
  • Why do we use nitric acid?

    This makes it important in the chemical and pharmaceutical industries. The most common use for nitric acid is to make fertilizer. One of the raw materials required to make an effective fertilizer is nitric acid, where it reacts with ammonia to produce ammonium nitrate.
  • What is the use of sulfuric acid?

    The major use of sulfuric acid is in the production of fertilizers, e.g., superphosphate of lime and ammonium sulfate. It is widely used in the manufacture of chemicals, e.g., in making hydrochloric acid, nitric acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs.
  • What makes sodium nitrate?

    Sodium nitrate (NaNO3) is a white solid at room temperature and is very soluble in water. Pure sodium nitrate is commonly used as a food preservative and rocket propellant. This reaction yields sodium nitrate and carbonic acid, which immediately decomposes into carbon dioxide (CO2) and water (H20).
B.

What metals will nitric acid dissolve?

Aluminum does not react; there is a barely perceptible reaction with zinc; and a strong reaction with copper continues. Concentrated nitric acid is a very strong oxidator capable of reacting with the noble metals such as copper or silver (not gold, however).
  • Why hydrogen gas is not involved when a metal reacts with nitric acid?

    Nitric acid(HNO3) is a strong oxidising agent. The Hydrogen gas produced during its reaction with metal gets oxidised to H2O, hence no hydrogen gas is produced. Instead it evolves nitric oxides such as NO2,NO etc.
  • What happens when zinc reacts with nitric acid?

    The products formed when zinc reacts with dilute nitric acid are zinc nitrate and hydrogen gas; i.e. 3Zn + 7HNO3 ---> Zn(NO3)2 + NH2OH + 2H2O; These products are formed due to the reduction of HNO3 by nascent hydrogen, which is produced in increasing amounts as the concentration of nitric acid is lowered; e.g.
  • How Nitric acid is formed?

    Production. Nitric acid is made by reaction of nitrogen dioxide (NO2) with water. Normally, the nitric oxide produced by the reaction is reoxidized by the oxygen in air to produce additional nitrogen dioxide. Bubbling nitrogen dioxide through hydrogen peroxide can help to improve acid yield.
