WebMar 2, 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. WebWhen you use a pH meter to measure pH, you want to be sure that if the meter says pH = 7.00, the pH really is 7.00. So you use solutions of known pH and adjust the meter to display those values. Buffers are ideal for this purpose because: They are easily prepared for a given pH. They are stable for long periods of time.
