pH levels measure how acidic or basic a solution is, on a scale from 0 to 14. A pH of 7 is considered neutral, meaning it is neither acidic nor basic. Solutions with a pH less than 7 are acidic, while those with a pH greater than 7 are basic. For example, lemon juice has a low pH and is acidic, while baking soda has a high pH and is basic. pH levels are important in various fields, including agriculture, biology, and environmental science. In agriculture, the pH of soil affects nutrient availability for plants. In biology, pH levels can influence enzyme activity and cellular functions. Understanding pH is essential for maintaining healthy ecosystems and effective agricultural
