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.
Red-brown liquid with a sharp, unpleasant chemical odor. Low-boiling (boiling point 21.15Â°C) and held as a liquid by compression. Density 1.448 g / cm3. Consists of an equilibrium mixture of brown NO2 (nitrogen dioxide) and colorless N2O4 (dinitrogen tetroxide). Evolves poisonous brown vapors.
