industrial preparation of ammonia and its uses

Uses of Ammonia - Following are the chief uses of ammonia: 1) Ammonia is used in the industrial preparation of nitric acid by Ostwald's process. 2) Fertilisers, such as ammonium sulphate, ammonium nitrate, ammonium phos..

In the manufacture of rayon and urea In the manufacture of fertilizers such as urea diammonium phosphate, ammonium nitrate, ammonium sulphate etc. In ice plants, as a refrigerant In furniture industry, as a cleansing agent for furniture and glass surfaces. In the manufacture..

The industries are mostly situated along the riverbanks for easy availability of water and also disposal of the wastes. But these wastes include various acids, alkalis, dyes and other chemicals. They change the pH of water. There are also detergents that create a mass of white foam in th..

Practically all industries use buffers in one process or the other. Major industries, which employ buffers are paper, dyes, ink, paints and drugs industries..

a) Metal casting can be tested for cracks by putting them in baths of radioactive salts. The castings are then inspected for radioactivity to find out any penetration of salts into cracks. Absence of salt penetration indicates absence of cracks. b) Radioactive isotopes can be used to det..

From Ammonical Liquor - During the destructive distillation of coal, ammonical liquor is obtained as a by-product. Ammonical liquor on further processing yields large quantities of ammonia and ammonium salts. Ammonical liquor is boiled with milk of lime to obtain ammonia. This i..

Ammonia - Ammonia was known to mankind since a long period, as it was produced in nature by putrefying and ammonifying bacteria. Chemical compound, NH 3 colorless gas that is about one half as dense as air at ordinary temperatures and pressures. It has a char..

3 ) Ammonia molecule has an electronegative nitrogen atom bonded to three hydrogen atoms. Differences in electronegativity between nitrogen and hydrogen makes each hydrogen atom acquires positive charge. Thus, in the molecule, there is one negative site and three positive..

Baking powder is used in all the food preparations. The addition of baking powder during baking, produces carbon dioxide which, makes the dough "rise". The small pores in a loaf of bread are the spaces in which carbon dioxide was formed (Fig.11.13). ..

3 ) molecule In forming a molecule of ammonia, '1s' orbital of each of three hydrogen atoms overlap with one of the three '2p' orbitals of nitrogen. This gives rise to three N-H sigma bonds oriented along three coordinate axes. The electronic configuration of ni..
