This value is considered neutral—neither acidic or basic. Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic.
CO2, SO2, and NO2 are all pollutants that react with water to form slightly acidic solutions. CO2 produces carbonic acid, which has a slightly higher pH than the sulfurous acid and nitric acid that's formed by SO2 and NO2. So these acidic solutions act as acid rain in the real world.
