What are the 4 major air pollutants?

What are the 4 major air pollutants?

The common air pollutants are:

  • Particulate matter (PM10 and PM2.
  • Ozone (O3)
  • Nitrogen dioxide (NO2)
  • Carbon monoxide (CO)
  • Sulphur dioxide (SO2)

What are the 5 air pollutants?

5 Major Outdoor Air Pollutants

  • Ozone (O3)
  • Nitrogen Oxides (NOx)
  • Carbon Monoxide (CO)
  • Sulfur Dioxide (SO2)
  • Particulate Matter (PM10 and PM2.5)

Which of the following is not a form of air pollution?

Nitrogen is not an air pollutant as the atmospheric composition contains 78% nitrogen and 21% oxygen by proportion. Oxides of nitrogen from external sources and carbon monoxide are various exhaust gases from vehicles which are air pollutants causing damage to the atmosphere.

Is acid rain a type of air pollution?

Acid rain is a result of air pollution. Power stations, factories and cars all burn fuels and therefore they all produce polluting gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids.

What is the chemical formula for acid rain?

1 Answer. Sulfuric acid ( H2SO4 ), nitric acid ( HNO3 ), and carbonic acid ( H2CO3 ) are the major components of acid rain.

Why Acid rain is harmful?

Acid rain can be extremely harmful to forests. Acid rain that seeps into the ground can dissolve nutrients, such as magnesium and calcium, that trees need to be healthy. Acid rain also causes aluminum to be released into the soil, which makes it difficult for trees to take up water.

Can acid rain kill you?

Can acid rain kill you? While acid rain can be incredibly detrimental for the environment and will kill many plants and animals over a long enough exposure, it won’t directly hurt or kill you.

What are the 3 causes of acid rain?

Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

What are 3 effects of acid rain in Germany?

It has damaged the soil and the trees growing in it. Many acres of diseased trees are at risk of dying. Sulfur and nitrogen gases found in acid rain eat holes in the surfaces of statues and buildings. Acid rain pollutes rivers, like the Danube and the Rhine, and kills the wildlife living there.

What is the effects of acid rain in Germany?

The acid rain caused massive devastation to trees, soils, rivers and lakes. By 1984 almost half of the trees in the nearby Black Forest showed signs of damage and images of blackened skeletal trees helped fuel the environmental movement.

When did acid rain in Germany start?

1950s

How do air currents contribute to the acid rain problem in Germany?

Air current carries the acid rain to countries that border Germany. Also carried down stream via the river. Air currents carry pollution to other countries. Radioactive material entered the air into northern Europe and Scandinavia.

Why has acid rain become an international problem?

Acid rain includes all types of precipitation with acidic content with a pH value of less than 7. Acid rain is referred to as an international problem because the emission of pollutants does not equally deposit in that country. Many countries emit a very small amount of pollutants and deposition can be greater.

Is acid rain still a problem in 2020?

The quick version: Yes, acid rain is still around, and yes it’s still a problem. The basics: Acid rain is a pretty straightforward appellation — it’s rain that’s been turned acidic by particles in the atmosphere. Rain is naturally slightly acidic, since picks up carbon dioxide in the air, producing carbonic acid.

What are the effects of acid rain on human?

While acid rain cannot harm humans directly, the sulfur dioxide that creates it can cause health problems. Specifically, sulfur dioxide particles in the air can encourage chronic lung problems, like asthma and bronchitis.

What Colour is acid rain?

When you add acid, bromothymol blue turns yellow; when you add a base (like sodium sulfite), it turns blue. Green means neutral (like water).

What is acid rain describe its effects?

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

What happens if acid rain touches you?

Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this, never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air. Unpolluted rain would have a pH value of between 5 and 6.

Is acetic acid present in acid rain?

Present in acid rain is CH3COOH.

What pH is acid rain?

4.0

Where is acid rain most common?

North Eastern United States

Why is the East Coast most affected by acid rain?

The acid rain comes from the slightly more western places where coal is mined, and then burned in “mine-mouth” coal plants, unsurprisingly located at the mine mouths. The winds tend to blow from west to east, so VA and MD get WV’s pollution, while the New England states get Ohio and PA’s pollution.

READ:   Why enzymes are known as biocatalysts?

How can you identify acid rain?

To know if a sample of rain is “acid rain” we need to measure the concentration of hydrogen ions in the sample. Hydrogen ions are produced when any acidic substance is dissolved in water. The solutions of some substances, like carbon dioxide in the air, are weakly acidic.

Which one of the following is not present in acid rain?

i) Carbonic acid ii) Sulphuric acid iii) Niric acid iv) None of the above. Acid rain contains mineral acids like carbonic acid, sulphuric acid and nitric acid.

Is h2co3 present in acid rain?

H2O (l) + H2CO3 (aq) ⇌ HCO3− (aq) + H3O+ (aq) Unpolluted rain can also contain other chemicals which affect its pH (acidity level). A common example is nitric acid produced by electric discharge in the atmosphere such as lightning.

Which gas is not present in acid rain?

Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Which one of the way can prevent acid rain?

A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.

Who first used acid rain?

Robert Angus Smith

In which South African province is the problem of acid rain particularly bad?

Acid particles in the air are suspected of contributing to respiratory problems in people. The coal burning power stations and large metal working industries of South Africa are concentrated in the Eastern Transvaal Highveld, the industrial heart of the country.

What is the pH value of normal rain Mcq?

Normal pH of rain is slightly acidic ~5.6 due to reaction of CO2 with rainwater. The pH of the acid rain drops below 5.6 and it becomes ~4.2 – 4.4.
