Physical Properties of Ammonia Chemistry Notes

Physical Properties of Ammonia :

  • Ammonia is a colourless gas with a characteristic pungent smell. It brings tears into the eyes.
  • It is lighter than air.
  • It is highly soluble in water due to the formation of hydrogen bonds.
    Physical Properties of Ammonia Chemistry Notes 1
  • It can be easily liquified at room temperature by the application of pressure because its vapour pressure is very high
  • Its freezing and boiling point is 198.4 K and 239.7K respectively
  • It’s solution is basic in nature due to the formation of OH ion. It also acts as base due to the acceptance of H+ ion.
    Physical Properties of Ammonia Chemistry Notes 2
  • Liquid ammonia when vaporised then it causes intense cooling so liquid ammonia is used as refrigerant.
