What Happens to the Reaction of Alkali with Ammonium Salt
Principle: Generally, ammonia can be prepared by heating an ammonium salt with any alkali. Ammonia is prepared in the laboratory by heating ammonium chloride and quick lime (CaO) or slaked lime [Ca(OH)2]. Chemical Reaction: 2NH4Cl+CaO = 2NH3+CaCl2+H2O or 2NH4Cl+Ca(OH)2 = 2NH3+CaCl2+H2O Ammonia is highly soluble in water and cannot be collected by water removal. Ammonia is lighter than air. Hence it is collected by the downward removal of air. Necessary Materials: A heat-resistant kettle, several gas jars, an exhaust tube bent at right angles, two test rods, a container, a…
