How is pH and acid precipitation diffeny?

pH is a measure of how acidic or basic a substance is on a scale from 0 to 14, with 7 being neutral. Acid precipitation refers to rain, snow, or fog with a pH lower than 5.6, which is caused by pollutants like sulfur dioxide and nitrogen oxides. Acid precipitation is one of the many factors that can lower the pH of water bodies, affecting aquatic life and ecosystems.
