laboratory preparation of ammonia gas

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 ..

In many industries, ammonia gas (NH 3 ) is used as reducing agent. It is a corrosive gas with a high potentiality of causing throat irritations, burning of pharynx, oesophagus, etc. It can also cause digestive problems - when excess gas i..

For use in the laboratory, ammonia is prepared by heating an ammonium salt with a strong base. It can also be prepared by reacting a metal nitride with water. All ammonium salts heated with alkali evolve ammonia. Ammonium nitrate is not used in ..

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..

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..

In laboratory, calcium sulphate is prepared by the action of sulphuric acid on calcium chloride, calcium oxide or calcium carbonate. ..

The figure shows the elements of a type of laser that is often found in student laboratories. The glass discharge tube is filled with a 80%-20% mixture of the inert gases helium and neon. Helium is the "pumping" medium and neon is the "lasing" medium. The above figure is a simplified vers..

A glass rod, dipped in concentrated hydrochloric acid when introduced into ammonia gas, produces thick white fumes of ammonium chlorid..

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 phosphate, urea etc. are manufactured with t..
