WebWhy does pH plus pOH equal 14? pH and pOH are the log concentrations of protons and hydroxide ions, respectively. The sum of pH and pOH is always 14. This is because the product of proton concentration and hydroxide concentration must always equal the equilibrium constant for the ionization of water, which is equal to . What is the H+ If the … WebMar 31, 2010 · pH=-log[H+] pH-log(1.2x10^-3) pH=2.92 since the the pH plus the pOH is always equal 14 14-2.92=11.08 so the pOH is 11.08 How does pH and pOH compare to one another?

WebAug 30, 2024 · The pH at the equivalence point is 7.0 because the solution only contains water and a salt that is neutral. Since neither H + nor OH-molecules remain in the solution, we can conclude that at the equivalence point of a strong acid - strong base reaction, the pH is always equal to 7.0.
