WebKw, the equilbrium constant for the autoionization of water (H2O = H^+ + OH^-is: Kw = [H^+] [OH^-] = 1.0E-14 at 25 deg C In a neutral solution, [H^+] = [OH^-] =1.0E-7 Thus, in a neutral solution, pH = -log [H^+] = 7.00 and pOH = [OH^-] = 7.00. In an acid solution, pH will be lower than 7.00 and pOH will be higher than 7.00. WebJan 26, 2024 · In water we assume that the concentration of [H3O+] = [OH-] (such as when Kw = 1.0 x 10^-14, [H3O+] = 1.0 x 10^-7 and [OH-] = 1.0 x 10^-7) so Kw = 2.1 x 10^-14 = [H3O+] [OH-] but since [H3O+] = [OH-] Kw = 2.1 x 10^-14 = x^2 so x = square root 2.1 x 10^-14 Then, you get the pH by taking the -log of x.
