How does the acid get into the atmosphere?

......When fossil fuels like coal, oil, and natural gas, are burned, sulfur dioxides and nitrogen oxides are released into the air. Any type of transportation that burns gasoline emits these fumes into the air. Gasoline is made from one of the major fossil fuels, oil.

.....Factories also burn fossil fuels. LIPA our electric company here on Long Island burns coal, another fossil fuel, to produce the electricity in your home. When sulfur dioxides and nitrogen oxides are released into the atmosphere they form acids.

How do these acids make acid rain?

.....These acids mix with the moisture in the air and fall back down to earth as acid precipitation. Otherwise know as "Acid Rain"

Is acid rain harmful?

.........Acid rain damages forests by changing the pH value of the soil. It does the same thing when it falls into the lakes and streams on earth. For example, let's say the water in your fish tank evaporates. As it evaporates instead of adding more fresh water pH(7) you add a weak acid like one of the ones we tested in school, orange juice or vinegar. Imagine how your fish would feel swimming in water that was very acidic. This is generally how acid precipitation kills aquatic life in the fresh water here on Earth. Acid rain can even damage statues, cars and buildings.

Is can you figure out how acidic the rain is?

If you look to the left of my web page you will see the pH scale. We used this scale to test many household items. Substances with a pH value of 1- 6 are considered acids. While substance with a pH value of 8 - 14 are basic or alkaline. The general rule is the further away the substance pH value is from 7 (neutral) the stronger is t is. For example. An acid with a pH of 3 is stronger than a an acid with a pH of 4. Because 3 is further away from 7. Same works for alkalines. An alkaline with a pH value of 14 is stronger than a substance whose ph value is 8, because 14 is further away from 7.

Here is the pH scale, like we used in class.
