Solution 2. The different forms of ammonia : Gaseous ammonia(dry ammonia gas) Liquid ammonia Liquor ammonia fortis Laboratory bench reagent Solution 3. Formula of liquid ammonia is: NH3. Liquid ammonia is liquefied ammonia and is basic in nature. It dissolves in water to give ammonium hydroxide which ionizes to give hydroxyl ions. Solution 4. Solution 5. (a) Lab preparation of ammonia: 2NH4Cl + Ca(OH)2 → CaCl2 +2H2O +2NH3 (b) The ammonia gas is dried by passing through a drying tower containing lumps of quicklime (CaO). (c) Ammonia is highly soluble in water and therefore it cannot be collected over water. Solution 6. The drying agent used is CaO in case of ammonia. Other drying agents like P2O5 and CaCl2 are not ...
