Why Ostwald process is used?

The Ostwald process is used to produce nitric acid. Ammonia is the feedstock for this reaction. It is reacted with oxygen and water using a platinum catalyst to produce nitric acid.

What do you mean by Ostwald’s process How will you manufacture nitric acid?

Nitric acid is manufactured by the Ostwald process, in which nitrogen oxide reacts with water. 3NO3​(g)+H2​O(l)→2HNO3​(aq)+NO(g)How many grams of nitrogen dioxide are required in this reaction to produce 25.2 g of HNO3​?

Can you make nitric acid from ammonia?

Nitric acid and ammonia are the two important reactive forms of nitrogen, which are widely used in human life and production. At present, the commercial nitric acid is produced through the oxidation of ammonia, which is called Ostwald process.

What is nitric acid used for?

Nitric acid is used for the production of ammonium nitrate, a major component of fertilizers. It is also used for producing explosives like nitroglycerin and trinitrotoluene (TNT) and for oxidizing metals.

Is the Ostwald process exothermic?

The Ostwald Process reaction is exothermic so external heat can be removed when the reaction gets started. In the Ostwald process nitrogen monoxide is initially formed then nitrogen dioxide dissolves in water. The reaction of nitric acid with ammonia to make ammonium nitrate is an example of a neutralisation reaction.

Which catalyst is used in Ostwald’s process of manufacturing nitric acid?

platinum catalyst
In Ostwald’s Process which catalyst is used? Ans: The process of ostwald is used to produce nitric acid. Feedstock is the ammonia for this reaction to occur. It is then reacted with water and oxygen using a platinum catalyst to produce nitric acid and this reaction is an exothermic reaction.

What is meant by contact process?

contact process, modern industrial method of producing sulfuric acid; it has largely replaced the chamber, or lead-chamber, process. Sulfur dioxide and oxygen, passed over a hot catalyst, unite to form sulfur trioxide, which in turn combines with water to make sulfuric acid.

How do you make nitric acid at home?

Dissolve 80 grams (2.8 oz) of nitrate salt in 50 millilitres (1.7 fl oz) of water. Start by portioning out your nitrate salt into a small glass mixing container. Then, pour in all of the water at once. Swirl the mixture around inside the container to help it dissolve faster.

How is nitric acid created?

Nitric acid is made by reaction of nitrogen dioxide (NO2) with water. The net reaction is: 3 NO2 + H2O → 2 HNO3 + NO. Normally, the nitric oxide produced by the reaction is reoxidized by the oxygen in air to produce additional nitrogen dioxide.

What are the main sources of nitric acid?

Most people are exposed outdoors to very minute amounts of nitric acid derived from exhaust fumes or the burning of some organic compounds that contain nitrogen. It is also present in small quantities in rain from areas where nitric oxide (a product of combustion) reacts with ozone and water to form nitric acid.

What is the Ostwald process and why is it important?

The Ostwald process has many well-known uses in both the industrial and health field. Through the Ostwald process, nitric acid is commonly used in fertilizers and pharmaceuticals, and because of it’s chemical reaction with some compounds it is used in rocket fuel and explosives like TNT (www.hpa.org.uk, n.d.).

What is the Ostwald process for nitric acid?

Ostwald Process. Ostwald process is one of the most common methods or chemical process used for the manufacturing of nitric acid. The process was developed in the year 1902 by a German chemist named Wilhelm Ostwald. He was later awarded the Nobel Prize in 1909 for his research.

What is Ostwald ripening?

Ostwald ripening is the process by which components of the discontinuous phase diffuse from smaller to larger droplets through the continuous phase. It was first described by the German scientist Wilhelh Ostwald, who is famous for receiving a Noble Prize “in recognition of his work on catalysis and for his investigations into

How do you calculate the overall reaction in the Ostwald process?

Alternatively, if the last step is carried out in air, the overall reaction is the sum of equation 1, 2 times the equation 2, and equation 4; all divided by 2. ^ Foist, Laura. “The Ostwald Process & Catalytic Oxidation of Ammonia”.
