Ammonia is a colourless gas with a characteristic pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at â33.3 Â°C (â27.94 Â°F), and freezes at â77.7 Â°C (â107.86 Â°F) to white crystals.
Ammonia dissolves easily in water to form ammonium hydroxide (NH4OH) and is often known in this form as 'household ammonia'. It is commonly used for cleaning. Today ammonia is used in the manufacture of dyes, explosives, plastics, drugs, nitric acid, fertilizer and many other chemicals that contain nitrogen.
