How nitric acid is manufactured?
How nitric acid is manufactured?
In general, the process for nitric acid manufacture consists of preheating the air, mixing it with ammonia gas, passing it over a platinum catalyst, extracting the heat produced from this reaction by using it to preheat the incoming air and then cooling further, adding secondary air and then absorb- ing the nitrogen …
How is nitric acid manufactured by Ostwalds’s process?
Nitric acid is most commonly manufactured by Ostwald process. The Ostwald process converts ammonia to nitric acid and involves two steps. In step 1, ammonia is oxidized to form nitric oxide and also nitrogen dioxide. Then in step 2, the nitrogen dioxide that was formed is absorbed in water.
How nitric acid is prepared in the laboratory?
Nitric acid is prepared in the laboratory by heating a nitrate salt with concentrated sulphuric acid. Vapours of nitric acid are condensed to a brown liquid in a receiver cooled under cold water.
Which catalyst is used for manufacture of nitric acid?
A catalyst used in the manufacture of nitric acid by Ostwald’s process is Platinum.
Which three materials are used during the manufacture of nitric acid?
Ammonia, oxygen, water are the raw materials of nitric acid manufacturing.
Which catalyst is used in Ostwald’s process for the manufacture of nitric acid?
Usually, in the Ostwald process ammonia is transformed into nitric acid. Vanadium pentaoxide (V2O5) is often used as a catalyst during the processing of nitric acid in this method.
What is the name of preparation of nitric acid?
The principal method of manufacture of nitric acid is the catalytic oxidation of ammonia. In the method developed by the German chemist Wilhelm Ostwald in 1901, ammonia gas is successively oxidized to nitric oxide and nitrogen dioxide by air or oxygen in the presence of a platinum gauze catalyst.
How is acid prepared in the laboratory?
(i) Synthetic Method – Acids are mostly prepared by a direct combination of elements. For example, hydrogen chloride gas is prepared from hydrogen and chlorine under the action of an electric spark. (ii) By dissolving acidic oxides in water: Some oxides get dissolved in water to form acids.
What are the raw materials required for the manufacture of nitric acid by Ostwald process?
What are the raw materials required for the manufacture of nitric acid by ostwald process. Ammonia, oxygen, water are the raw materials of nitric acid manufacturing. Ammonia can be obtained by haber process. Ammonia gas is oxidized to nitrogen dioxide by oxygen.
What is the catalyst used in Haber process?
iron
The catalyst used in Haber’s process in a metal catalyst. Usually, iron is widely used as a catalyst in this process. Iron has been preferred because it helps to achieve an acceptable yield of a product in a much faster time.
What is manufactured by Haber process?
In the Haber process for manufacturing of ammonia, nitrogen combines with air to form ammonia. The reaction is a reversible reaction and is exothermic in nature. As it is an exothermic reaction, high temperature is required.
Which catalyst is used in Ostwald’s method?
Vanadium Pentoxide is used as a catalyst in Ostwald’s process.
How nitric acid is prepared by Ostwald process give chemical equation of the related reaction?
3NO2(g)+H2O(g)→2HNO3(l)+NO(g)
Which catalyst is used for the manufacture of nitric acid?
How do you make nitric acid solution?
Add 64.1mL, or 90.4g, of SEASTAR™’s Nitric Acid to water up to 1L to make a 1 Molar Solution of Nitric Acid.
What are the methods of preparing acid?
Methods of Preparing Acids
- (1) By dissolution of acid anhydride. CO2(g) + H2CO3(g)
- (2) By combination of constituent elements. H2(g) + H2O(L) 2HCL(g)
- (3) By the use of stronger acids with salts of weaker ones so as to liberate the weaker acids. 2Nacl(ag) + H2SO4(ag) Na2SO4(ag) + 2HCL(ag)
Which catalyst is used for manufacturing of nitric acid?
What is manufactured by Haber’s process?
The Haber process for the synthesis of ammonia is based on the reaction of nitrogen and hydrogen.
Why is Fe used in Haber process?
Explain why iron is used in the Haber process. Iron is a catalyst for the reaction. It increases the rate of the reaction without being used up in the reaction.
How is nitric acid prepared from catalytic oxidation of ammonia?
When ammonia reacts with oxygen in presence of platinum catalyst it forms nitrogen oxide. In the second step, the nitrogen oxide gas converts into nitrogen dioxide, and this nitrogen dioxide gas reacts with water to form nitric acid.
