Acid rain was first noticed and studied in 1872. The formation of acid rain starts as soon as polluting chemicals namely nitrogen and sulphur oxides emissions from factories and car engines are sent up into the atmosphere. When these pollutants reach the atmosphere, they combine with existing water vapors, oxygen and sunlight. The reaction creates a diluted ‘soup’ of highly dangerous sulphuric, nitric and hydrochloric acids. When it rains, it washes down this highly dangerous acidic soup on which is known as acid rain. Acid rain changes the soil nutrient content, kills large stretches of forests and can also cause skin irritation.
