How to find pOH: Introduction of pOH, pOH from Molarity, pOH

Webb16 aug. 2024 · 14.00 = pH + pOH. The hydronium ion molarity in pure water (or any neutral solution) is 1.0 × 10 − 7 M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: pH = − log[H3O +] = − log(1.0 × 10 − 7) = 7.00. pOH = − log[OH −] = − log(1.0 × 10 − 7) = 7.00.
