WebbAt 25 °C, the value of Kw is 1.0 × 10 −14, and so: 14.00 = pH + pOH 14.00 = pH + pOH. As was shown in Example 1 in Chapter 14.1 Brønsted-Lowry Acids and Bases, the hydronium ion molarity in pure water (or any neutral solution) is 1.0 × 10 −7M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: WebbCalculate concentration of KOH when pH 10 at 25 0 C. Here, we are given the pH value of aqueous KOH solution. Now, we have to calculate the concentration of KOH. If we know the pH value, we can calculate pOH from the relation of pH, pOH and pKw. pH + pOH = 14 at 25 0 C. So pOH = 4; From pOH equation, we can calculate OH-concentration.
