Webp K w = pH + pOH At 25 °C, the value of Kw is 1.0 × 10 −14, and so: 14.00 = pH + pOH As was shown in Example 14.1, 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 [ H 3 O +] = −log ( 1.0 × 1 0 −7) = 7.00 WebpOH= −log[OH−] = −log(4.9×10−7) = 6.31 pOH = − log [ OH −] = − log ( 4.9 × 10 − 7) = 6.31. At this temperature, then, neutral solutions exhibit pH = pOH = 6.31, acidic solutions exhibit …
