Why do scientist use the pH scale?

Scientists use the pH scale to measure the acidity or basicity of a solution. This scale helps to quantify the concentration of hydrogen ions in a solution, which is important in various fields such as chemistry, biology, and environmental science. By knowing the pH of a solution, scientists can understand how it may interact with other substances or organisms.
