preparation of ammonium nitrate and ammonium sulphate

Ammonium sulphate is prepared by treating sulphuric acid with ammoni..

Ammonium nitrate is prepared by treating ammonia or ammonium hydroxide with nitric acid. It is a colorless crystalline solid, very highly soluble in water. When heated, it first melts and then decomposes as follows:..

Hydrogen peroxide can be prepared on a large scale by the electrolysis of ammonium hydrogen sulphate dissolved in excess of sulphuric acid, using platinum electrodes and a high current density. In order to have high current density (i.e., current strength per unit are..

When a mixture of ammonium sulphate and powdered calcium carbonate are heated and the vapour condensed, ammonium carbonate or sal volatile is obtaine..

Ammonium chloride is a compound of ammonia containing the chloride radical Cl 2 . Ammonium chloride, when heated, undergoes thermal dissociation, to form ammonia and hydrogen chloride. Ammonia and hydrogen chloride recombine at the cooler upper parts of the test tube, and settl..

Ammonium dichromate is a compound of ammonia containing the dichromate radical . It is an orange coloured crystalline substance. When heated, it starts decomposing with sparks and evolution of heat. The reaction then proceeds with its own heat, and a greenish fluffy powder called chromic..

Ammonium nitrite on heating decomposes to form nitrogen...

(i) By treating excess ammonia with chlorine, ammonium chloride and nitrogen are formed. The products obtained are bubbled through water. The vapours of ammonium chloride dissolve in the water while nitrogen is collected separately. (ii) By passing ammonia over heated metallic o..

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 ammonia is lighter than air, it is collected by the downward displac..

The hydronium ion is a hydrogen ion in association with a molecule of water. In a water molecule, the oxygen atom has two pairs of unshared electrons in its outermost shell. The hydrogen ion does not have any electron in its valence shell. Hence it shares a pair of electrons from the oxygen a..
