WebAug 4, 2024 · 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. And so, at this temperature, acidic solutions are those with ... WebThe correct pH measurement is 7 for D.I. water, and the effect of carbon dioxide should be ignored.
