What does "pH" stand for?
“pH” stands for “potential of hydrogen.” It is a measure of the acidity or alkalinity of a solution, and is often used to describe the acidity or alkalinity of water-based solutions such as drinking water, swimming pools, and soil. The pH scale ranges from 0 to 14, with 7 being considered neutral. A pH value less than 7 is acidic, while a pH greater than 7 is alkaline or basic. The pH of a solution is determined by the concentration of hydrogen ions (H+) in the solution. A solution with a high concentration of H+ ions is acidic, while a solution with a low concentration of H+ ions is alkaline or basic. pH is an important factor in many biological and environmental processes, as it affects the behavior of chemicals and nutrients in the soil, water, and living organisms. Maintaining the correct pH balance is important for optimal health and functioning of organisms and ecosystems.
