Acid rain is made from chemicals in the air mixing with water in the air. This makes the rain more acidic then normal rain.
Two elements found in unpolluted air are nitrogen, which makes up about 78% of the atmosphere, and oxygen, which makes up about 21%. These two elements are crucial for supporting life on Earth.
Acid rain" is a popular term referring to the deposition of wet (rain, snow, sleet, fog and cloudwater, dew) and dry (acidifying particles and gases) acidic components. A more accurate term is "acid deposition". Distilled water, which contains no carbon dioxide, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are bases. "Clean" or unpolluted rain has a slightly acidic pH of about 5.2, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid (pH 5.6 in distilled water), but unpolluted rain also contains other chemicals.[1]
Two pollutants found in air that can make rain water more acidic are sulfur dioxide and nitrogen oxides. These pollutants can react with water in the atmosphere to form sulfuric acid and nitric acid, which then fall to the ground in the form of acid rain.
Normal rain is slightly acidic, with a pH around 5.6 due to the natural presence of carbon dioxide in the atmosphere. Acid rain, on the other hand, has a lower pH (below 5.6), caused by pollutants such as sulfur dioxide and nitrogen oxides reacting with water in the atmosphere.
The gas from the air that dissolves in rain to make it slightly acidic is carbon dioxide (CO2).
Normal rain is slightly acidic but it occurs naturally, as oppose to acid rain caused by air pollution
When there are too much toxins in the air, rain becomes somewhat acidic.
S02 is produced by mold. It makes the rain water acidic because when it rains the dirt and pollution in the air are collected and when it floods the pollution an the ground is collected in the water.
The pollutants in air make rain water acidic. Rain water, containing acid reaches everywhere .
Oxygen and nitrogen are two main elements found in unpolluted air. Oxygen is needed for respiration by humans and animals, while nitrogen makes up the largest portion of the Earth's atmosphere and is essential for plant growth.
