Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone ( SOý, NOx, and Oý ) is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren’t absorbed into clouds, they can drift for miles and fall to the ground, resulting in Acid Deposition, or dry deposition. When Acid Rain falls into water it is mixed in with the normal water and causes the pH of the entire body to be raised. Measurments on the pH (potential Hydrogen ) scale, rise exponentialy, thus, a lake with a pH of 4 is ten times as acidic as a lake with a pH o
