Webb3 aug. 2007 · To add to Christina's post, pKw = -log Kw = -log 2.92 x 10^-14 = 13.53 so at pH = pOH = 6.77 then pH + pOH = 6.77 + 6.77 = 13.54. You WON'T get 14 for pKw because it isn't at room temp. That's why Kw isn't listed as 1 x 10^-14. Thanks so much!

WebbpH = -log [H+] HCl is a strong acid, completely dissociated in water. Therefore, a concentration of HCl = 2*10^-8 M H2O dissociates (H2O = H+ + OH-, Ka = ~10^-14) and therefore, water contributes 10^-7 M H+. Normally, this is small compared to the concentration of the acid and is not a consideration. WebbIf HCl solution has a high concentration such 0.1, 0.01 mol dm-3, pH value is increased by 1 when concentration is reduced from 10 times. When HCl concentration is too low like …
