WebMar 28, 2024 · 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 … WebJan 6, 2024 · pOH is a less-known scale for determining the acidity or alkalinity of a solution. Analogous to pH, you can calculate pOH as the negative logarithm of the hydroxide ion OH - concentration: \small pOH = -log ( [OH^-]) pOH = −log( [OH −]) pH and pOH are related at 25°C, so by knowing one value you automatically get the value of the other:
