The range that is considered alkaline on the pH scale is from 7 to 14. pH is a measure of the acidity or alkalinity of a solution, where a pH below 7 indicates acidity, a pH of 7 is neutral, and a pH above 7 indicates alkalinity. Solutions with a pH higher than 7 have a lower concentration of hydrogen ions compared to hydroxide ions, making them basic or alkaline. This understanding of pH is crucial in many fields, including chemistry, biology, and environmental science, as it affects chemical reactions, biological processes, and the behavior of various substances in nature.
