Atmospheric Physics
The pH level is a measure of how acidic or basic a solution is, indicating the concentration of hydrogen ions present. It is represented on a scale from 0 to 14, where a pH less than 7 indicates acidity, a pH of 7 is neutral, and a pH greater than 7 indicates alkalinity. This measurement plays a crucial role in understanding environmental phenomena, particularly in the context of acid rain and its impact on ecosystems.
