What produces the most nitric acid?
fertilizers
The most important industrial use of nitric acid is the preparation of the salt ammonium nitrate, NH4NO3, which is used in the manufacture of fertilizers and explosives. In fact, more than 80\% of the nitric acid produced annually is devoted to the preparation of fertilizers.
Is nitric acid pure?
Nitric acid (HNO3), also known as aqua fortis (Latin for “strong water”) and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water.
How does the Birkeland Eyde process work?
Birkeland used a nearby hydroelectric power station for the electricity as this process demanded about 15 MWh per ton of nitric acid, yielding approximately 60 g per kWh. This nitrogen dioxide is then dissolved in water to give rise to nitric acid, which is then purified and concentrated by fractional distillation.
How nitric acid is produced?
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.
What household item has nitric acid?
Table 7: Alkalis and acids frequently found in household products
| Alkalis | Products |
|---|---|
| Acids | Products |
| Sulfuric acid Hydrochloric acid Sodium bisulfate Sodium hypochlorite Acetic Acid Nitric acid | Drain cleaner Toilet bowl cleaner House bleach (low concentration) Descalers |
How do you distill nitric acid?
The simplist and most used preparation of nitric acid in the lab is by adding concentrated sulfuric acid to a dry nitrate salt, usually, potassium or sodium nitrate. This mixture is heated to melt the pasty mixture and distill the nitric acid.
How do you check the purity of nitric acid?
Also it can be measured in baumé or in specific gravity. An old fashioned way is 10 ml of solution in 100 ml distilled water, a couple of drops of methyl orange indicator, titrated with 1N sodium hydroxide from a red to a yellow orange end point.
Which raw material is used in Birkeland Eyde process?
Dinitrogen
Dinitrogen is prepared commercially from air by liquification and fractional distillation. When liquid air is allowed to distil, dinitrogen having lower b.pt (77K) distils over first leaving behind liquid oxygen (bpt 90K).
