WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion … WebMar 28, 2024 · p O H = − log [ 10 − 7] = − ( − 7) = 7. Thus, both the pH = 7 and pOH = 7 for pure water. This makes sense, since the pH and pOH should sum to 14, as shown in Equation 15.8. 3 above. As previously noted, temperature matters. However, if the temperature is not cited, a temperature of 25°C (room temperature) may be assumed.
