What causes smog and acid rain? … Photochemical smog is caused by nitrogen oxides combing with sunlight and other pollutants. Acid rain is caused by sulfur oxides and nitrogen oxides combining with water.
What is one difference between acid rain and smog?
The pollutants in smog come from vehicle emissions, smokestack emissions, paints, and solvents – most of which started out as crude oil. … The pollutants of acid rain are derived from coal fired power plants.
What are acid rain and smog?
Air pollution, which can lead to smog and acid rain, is the result of adding compounds or particles to the air that are harmful to human health or the environment. The most obvious danger of air pollution is that humans and other animals inhale pollutants and can become ill.
Is smog and acid rain bad?
Acid Rain Can Cause Health Problems in People
Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Respiratory diseases like asthma or chronic bronchitis make it hard for people to breathe.
What is the relationship between smoke and acid rain?
Acid rain occurs in industrial areas when the atmosphere is very polluted with smoke from very large numbers of factories and cars. The chemicals present in smoke pollution dissolve in the water in clouds to produce rainwater that is acidic.
Which gases causes smog and 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.
How are the causes of smog and acid rain Similar How are they different?
London-type smog is caused by soot left in the air from burning coal. Photochemical smog is caused by nitrogen oxides combing with sunlight and other pollutants. Acid rain is caused by sulfur oxides and nitrogen oxides combining with water. … The air is still polluted in many cities.
What is acid rain explain?
Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
Can acid rain burn your skin?
Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this; it is never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air.
Why is smog and acid rain not regulated?
Acid rain occurs when emissions from vehicles and industry sources interact with chemicals in the atmosphere. … Though the Clean Air Act of 1972 has reduced the amount of sulfur dioxide and nitric oxides entering the atmosphere, a new player, ammonia, is adding to the pH imbalance and is not currently regulated.
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.
What are 3 effects of acid rain?
Acid rain has been shown to have adverse impacts on forests, freshwaters, and soils, killing microbes, insects and aquatic life-forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.
Why Photochemical smog is called so?
-Chemicals require sunlight for the reaction that is sun plays a very important role in the chemical reaction. This chemical reaction is called photochemical reaction and the smoke which is formed by this photochemical reaction is known as photochemical smog.
What is the chemistry behind the difference of pH between normal rainwater and acid rain?
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.
Are clouds acidic?
Clouds and fogs are also generally acidic, but to a lesser degree than particles, and have a range of pH that is quite sensitive to anthropogenic emissions of sulfur and nitrogen oxides, as well as ambient ammonia.
