which of the following statements about the concentration of acid rain in the u.s. is most accurate? high acid rains levels (e.g. pH <5) occur along the appalachian mountains, a considerable distance from the midwestern manufacturing regions from which these pollutants derive Acid rain is measured on the pH scale. The lower the values, the higher the acidity. Normal rain has a pH of about 5.6 (slightly acidic due to CO2 dissolving to form a weak carbonic acid). Which of the following statements about the concentration of acid rain in the U.S. is most accurate Acid Rain and the pH Scale. The pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic

Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality

Acid rain has a pH of 5.0 or less. Most acid deposition ranges from pH 4.3 to 5.0 -- somewhere between the acidity of orange juice and black coffee. But comparing acid rain to safe, natural acids can be misleading. Even at its weakest, acid rain wrecks ecosystems by stunting sensitive plants and killing delicate aquatic eggs
