WebMay 11, 2016 · pOH = 14 − pH Explanation: You can simply find the pH from the concentration of H + which is equal to: [H +] = [H Cl]0 Then, pH = − log[H +] From the water dissociation constant kw = [H +][OH −] = 1.0 × 10−14 we can take the −log of both parties, we get: −logkw = −log[H +] −log[OH −] = 14 WebThe acidity of a solution is typically assessed experimentally by measurement of its pH. The pOH of a solution is not usually measured, as it is easily calculated from an experimentally determined pH value. The pH of a solution can be directly measured using a pH meter ( Figure 15.2.3 ). Figure 15.2.3.
