Acid Rain: The natural rain's pH is 5.6, but acid rain even goes to the 4s. pH of 4 is ten times more acidic than pH 5, and pH 10 is ten times more basic than pH 9, and so on and so forth. The composition of the acid in acid rain is mostly sulfuric acid (H2SO4), and nitric acid (HNO3) that comes from cars and factories. This joins with the water vapor and droplets in the air, and falls as acid rain. When there is acid rain and groundwater pollution, the soil also gets acidic, and the soil could contribute to the corrosive effect for ground metals.
