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.
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.
Liquid ammonia when vaporised then it causes intense cooling so liquid ammonia is used as refrigerant.
