WebAt 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. WebWhy do you need to pay close attention to your Drinking Water?
