Verizon LTE 1:50 PM * 62% sfccmo.blackboard.com Acid Rain Activity Sulfur dioxide and nitrogen oxides are gases released by the burning of fossil fuels. These gases can react with water and oxygen to form acids. Normally, rainwater is slightly acidic. But the additional acid that enters the air when fuels are burned makes it even more acidic. Acid rain can have a harmful effect on fish and other wildlife and upsets the delicate balance of a forest or aquatic ecosystem. The good news is that it works the other way, too. Decreasing car and factory emissions can reduce acid rain and help wildlife. In this activity, you'll find out more about what acid rain is, where the problem is most severe, and what YOU can do to help. Answer the questions below. I have embedded links in this document to appropriate information online. If you click on the underlined blue text (you may have to hold down Ctrl while clicking on the blue link), you will open up online information that you will need to answer these questions. If you have problems with these links, please let me know. You can also check out an acid rain animation here . First, let's take a look at which parts of the country are having the biggest acid rain problem. View a color-coded pH map (click here) of the United States. The darker orange colors represent the lowest pH in rain. Which states have the worst acid rain problem? 2 Next, go to the EPA's What is Acid Rain? (click here) page. What is the difference between wet deposition and dry deposition? How do the compounds that cause acid rain spread from their source? The two main gases that cause acid rain are and s. What percentage of each of the two gases you listed in

Explanation / Answer

1) East Coast is the region of the United States most harmed by acid rain, including the Appalachian Mountains and the Northeast. Levels of nitric and sulfuric acid in precipitation have been steadily increasing since the year 2000 in Asian cities such as Beijing and New Delhi due to increase in demands for electricity and goods.

2) Acid rain is an acidic rain due to some air pollutants. Acid rain is a type of acid deposition, that have many forms. Wet deposition means more acidic rain,snow, sleet, than normal. Dry deposition means acidic gases and dust particles.

3) Wind can carry both deposition wet and dry, sometimes for very long distances. Wet Acid deposition falls on buildings, cars, and trees and can make lakes acidic. Dry acid deposition can be inhaled and can cause health problems in some people.

4) sulfur dioxide (SO2) and nitrogen (NOx) are 2 major gases that causes acid rain.

5) Fossil fuels burns to generate electricity. Electric power generators generates 2/3 of SO2 and 1/4 of NOX in the atmosphere.

6) SO2 and NOX react with water, oxygen to form sulfuric and nitric acids.

7) mild solution of  sulfuric and nitric acids.

8) normal rain - ph 5.6 - acidic, acid rain - ph 4.2 to 4.4 - more acidic, lemon juice - ph 2 - most acidic, soda - ph 9 - alkaline, blood - ph 7.35 - almost neutral, ammonia - ph 11- more alkaline.
