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 characteristic pungent, ..

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..

By Heating any Ammonium Salt with an Alkali - In the laboratory, ammonia is usually prepared by heating a mixture of ammonium chloride and slaked lime in the ratio of 2 : 3 by mass. The arrangement of the apparatus is shown in the figure 6.2. As ammoniah..

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 phosphate, urea etc. are manufactured with the help of ammonia..

Ammonia (NH 3 ) - Ammonia (NH 3 ) is an important compound of nitrogen and hydrogen. It is produced by the natural decomposition of animal and vegetable bodies. The death and decay of plants and animals cause the nitrogen compounds present..

Gaseous ammonia is a pungent, irritant gas often causing effects like skin irritation, eye irritation and irritation to throat. It can cause number of allergies. ..

Ammonia (NH 3 ) is an important compound of nitrogen and hydrogen. It is produced by the natural decomposition of animal and vegetable bodies. The death and decay of plants and animals cause the nitrogen compounds present in them to get decomposed, giving am..
