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.
For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5-8.3 at 25 Â°C (77 Â°F). Neutral litmus paper is purple.
