2. What is Acid Rain?
The term "acid rain" means the deposition of acidic components in rain, snow, fog, dew, or dry particles.
Distilled water, which contains no carbon dioxide, has a neutral pH of 7.
"Clean" or unpolluted rain has a slightly acidic pH of 5.6, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid.

3. What Causes Acid Rain?
Acid deposition primarily results from the transformation of sulphur dioxide (SO2) and nitrogen oxides into dry or moist secondary pollutants such as sulphuric acid (H2SO4), ammonium nitrate (NH4NO3) and nitric acid (HNO3).

5. Where is Acid Rain the most?
The area most effected in the United States is the Northeast Region.

6. How it effects the people?
Many scientific studies have identified a relationship between elevated levels of fine particles and increased illness and premature death from heart and lung disorders, such as asthma and bronchitis.
Hospital admissions for heart and respiratory problems, increased asthma-symptom days, as well as higher death rates from these ailments.

7. Acid Rain and air quality
Burning fossil fuels also creates urban smog and climate change and releases mercury into the air.
When air becomes polluted, more citizens are vulnerable to sicknesses.

8. What does Acid Rain do to trees?
The impact of acid rain on trees ranges from minimal to severe, depending on the region of the country and on the acidity of the rain.
Soil loses more nutrients depending on the acidity of the rain.

9. Trees effected by acid rain.

10. Water
Wildlife in lakes and rivers is effected by acid.

11. Solutions Reduced uses of emissions
Power plants can burn coal with a low percentage of sulfur.
Use Scrubbers- are like "liquid" filters for the gases resulting from combustion.
Fluidized Bed Combustion- a turbulent bed of pulverized coal and limestone is suspended by an upward blast of air.
Decrease reliance on coal- fired plants for electricity. Ex. Start to use hydroelectricity and solar power energy.
