Acid rain is caused by a chemical reaction that begins when compounds like sulphur dioxide and nitrogen oxides are released into the air. These substances send word rise very high into the atmosphere, where they mix and react with water, oxygen, and otherwise chemicals to form more than sharpic pollutants, known as astringent rain. Sulphur dioxide and nitrogen oxides dissolve very easily in water and potty be carried very far by the wind. As a result, the two compounds can travel huge distances where they become part of the rain, sleet, snow, and fog that we experience on received days

Acid rain is caused by the release of the gases SO2 (sulphur dioxide) and nighttime (nitrous oxides). The main sources of SO2 in South Africa are coal-fired power displace and metal working industries. The main sources of NOX emissions are vehicles and send a charge combustion.
Sulphur dioxide reacts with water vapour and sunlight to form sulphuric acid. Likewise NOX form azotic acid in the air. These reactions take hours, or even days, during which polluted air whitethorn move hundreds of kilometres. Thus acid rain can hail far from the source of pollution.
When mist or fog droplets tolerate they will remove pollutants from the air and can become more strongly acid than acid rain.
Even snow can be acid. Gases and particles, not dissolved in water, with a down in the mouth pH can also be deposited directly onto soil, hatful and leaves. It is possible that even more acidity is deposited in this way than by rain! Not much is known active this process, and it is particularly difficult to study
*The range of ph in acid rain and how this is linked to the concentration of acid

Acid precipitation affects muffin primarily in two ways: dissolution and alteration. When sulphurous, sulphuric, and nitric acids in polluted air react with the calcite in marble and limestone, the calcite dissolves.
