Web20 mei 2024 · pKw = pH + pOH At 25 °C, the value of Kw is 1.0 × 10 − 14, and so: 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 Web17 mrt. 2024 · Poh Sing Ng .

Because the constant of water, K w is \(1.0 \times 10^{-14}\) (at 25° C), the \(pK_w\) is 14, the constant of water determines the range of the pH scale. To understand what the pK w is, it is important to understand first what the "p" means in pOH and pH. The addition of the "p" reflects the negative of the logarithm, \(-\log\). Therefore, the pH is the … lowkey rich
