WebJul 20, 2024 · Therefore the definitions of pH and pOH mean that we can deal with powers of 10 rather than numerical values. Since the numbers needed to express [H 3 O +] and [OH –] are usually between 1 and 10 -14 pH and pOH values are usually between 0 and 14. Example \PageIndex {1}: pH & pOH 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. How to Measure pH
