WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. WebApr 9, 2024 · The pH scale is the measurement of how acidic or basic a substance is. It specifically measures the amount of free hydrogen ions found in a solution. Although it sounds contradictory, substances with a low pH (below 7) have more free hydrogen ions and are considered acids.
