Webp Kw = pH + pOH At 25 °C, the value of Kw is 1.0 × 10−14, and so: 14.00 = pH +pOH As we learned earlier, 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 × 10 −7) = 7.00 WebFeb 27, 2024 · pH and pOH of a solution: pH of a solution: The negative logarithm to the base 10 of molar concentration of H + ions in a solution is called as pH of a solution. Mathematically, pH = – log 10 [H +] For pure water or a neutral solution.at 298 K. [H +] = 1 x 10 -7 moles/dm3 ∴ pH = – log 10 (1 x 10 -7 ) = – (-7) log 10 10 = + 7 (1) = 7
