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. … WebSep 30, 2024 · These are acids. Chemicals that accept hydrogen ions have higher pH values and are bases. Because bases don’t have free hydrogen ions, it’s sometimes easier to calculate pOH. pOH is a measure of the hydroxide ion (OH –) concentration. pOH = -log[OH –] pH and pOH are related. At room temperature: pH + pOH = 14.
