As is seen in Table I, carbon dioxide (CO2) is present in the greatest concentration and therefore contributes the most to the natural acidity of rainwater.
Is carbon dioxide part of acid rain?
The lower a substance’s pH (less than 7), the more acidic it is; the higher a substance’s pH (greater than 7), the more alkaline it is. Normal rain has a pH of about 5.6; it is slightly acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid. Acid rain usually has a pH between 4.2 and 4.4.
What are the main components of acid rain?
Sulfuric acid, Nitric acid and carbonic acid are the major components of acid rain. The two strong acids present in the acid rain are nitrogen oxide and sulphur dioxide. These two gases react with water in the atmosphere and oxygen in the air to form sulphuric acid and nitric acid.
What are 3 causes of acid rain?
Human activities leading to chemical gas emissions such as sulfur and nitrogen are the primary contributors to acid rain. The activities include air pollution sources emitting sulfur and nitrogen gases like factories, power generation facilities, and automobiles.
Which gas is not responsible for acid rain?
Carbon dioxide reacts with water to form carbonic acid thus contributing to acid rain. So, from all these gases only carbon monoxide does not react with water to form an acid. Thus, not contributing to the acid rain, So, the correct answer is “Option C”.
Is acid rain an acid or base?
Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.
Is carbon dioxide a secondary pollutant?
Carbon Monoxide (CO)
Carbon monoxide is released from volcanoes and forest fires as well. Secondary pollutants like ozone and carbon dioxide (CO2), a greenhouse gas, come from carbon monoxide.
Which of the following are natural causes of acid rain?
The precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion.
What is acid rain kid definition?
Acid rain is a form of air pollution. When coal and petroleum are burned in automobiles, electric power plants, and factories, they release certain harmful gases into the air. … When the water in the air comes down as rain, sleet, hail, or snow, it carries with it these gases. This is known as acid rain.
What are the 2 most common forms of acid deposition?
Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry.
Which of the following is responsible for acid rain?
The correct answer is Sulphur dioxide. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
Does Co cause acid rain?
Carbon Monoxide (Co)
Carbon monoxide gas is produced by the incomplete combustion of hydrocarbon fuels (petrol and diesel) in vehicle engines. The carbon monoxide gas is then oxidised to carbon dioxide gas, which reacts with water particles in the upper atmosphere to produce carbonic acid (acid rain).
Does methane contribute to acid rain?
These non-toxic gases, most of which occur naturally in the atmosphere and are not pollutants, include carbon dioxide, methane, CFCs, and nitrous oxide. Acid rain is caused by toxic industrial smoke containing sulphur dioxide, nitrogen oxides, and chloride.
