Acid Rain- What is it?

What Makes Rain Acid?

Sulfuric Acid in Rain S(s) + O 2(g) ==> SO 2(g) The SO 2(g) combines with water to produce sulfurous acid. H 2 O(l) + SO 2(g) ==> H 2 SO 3(g) Or H 2 O(l) + SO 3(g) ==> H 2 SO 4(aq)

Nitric Acid Formation N 2(g) + O 2(g) ==> 2 NO(g) Nitrogen dioxide combine with water vapor to produce nitric acid 2 NO 2(g) + H 2 O(l) ==> HNO 3(aq) + HNO 2(g)

Acid Raining on Us You are given 4 samples from fresh water bodies from different places in New England. • Create a guideline for healthy water p. H. Test each sample of water and label it as a healthy water system according to your guidelines. • With your group, hypothesize about the factors that make the water samples different. Write these down to share with the class.

What’s your p. H?

TAKE A STAND! Rain is naturally a little acidic and acids are naturally occurring, even in many of the foods that we eat. Some people think that acid rain isn't nearly as big of a deal compared to other environmental issues. Do you agree, or disagree?

Do you think it is fair to place limits on developing countries, where people are struggling for food and shelter, and simply trying to make their lives move like ours? Developed countries, such as the U. S. and many countries in Europe all had time to develop without environmental regulations. Should developing countries be allowed to do the same?

In the “cap and trade” system, each company that causes air pollution is permitted a certain amount of air pollution credits according to their current pollution. These pollution credits can be bought and sold. Do you agree or disagree this is a good way to limit air pollution?

What do you see as a greater environmental issue, acid rain or ocean acidification?
