effects of oxides of nitrogen to the environment.
Properties
Nitrogen monoxide( NO)
NO: sharp, sweet-smelling, colourless gas
Melting point: -163.6°C
Boiling point: -151.8°C
Relative Density: 1.04 (air = 1)
Nitrogen dioxide (NO3)
NO2: reddish-brown gas with irritating odour.
Melting point: -9.3°C
Boiling point: 21.15°C
Vapour Density: 1.58
Sources
Nitrogen dioxide (NO3)
When Nitrogen monoxide is released from the engines of vehicles, it combines with Oxygen in the air to form Nitrogen dioxide
Nitrogen Monoxide + Oxygen → Nitrogen Dioxide
2NO (g) + O2 (g) → 2NO2 (g)
Nitrogen monoxide
When fuels are burned in car engines, high temperatures are reached which allows Nitrogen and Oxygen from the air to combine to produce Nitrogen monoxide
Nitrogen + Oxygen → Nitrogen Monoxide
N2 (g) + O2 (g) → 2NO (g)
Acid rain
Impact
Kills trees
Leaches minerals and nutrients out of the soil and causes plants and trees to die. Also leaches aluminum from soil which can be toxic to the plants. Damages waxy layer of leaves, making it difficult for trees to absorb mineral ions they need for growth.
Kills aquatic marine life
Makes rivers and lakes too acidic, resulting in the deaths of aquatic organisms
Destroys buildings
Corrodes metal like steal and limestone by reacting with metals and carbonates
How
Nitrogen oxides will dissolve in water droplets in clouds, forming dilute Nitric acid and Nitrous acid, causing acid rain
Nitrogen Dioxide + Water → Nitric Acid
NO2 (g) + H2O (l) → HNO3 (aq)
