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 . Web=>pK w = pH + pOH = 14 The value of pK w controls the relative concentrations of hydrogen and hydroxyl ions as their product is always constant. pH of acids and bases can be roughly calculated with the help of pH scale while for accurate values we use pH meters. pH Example Chart pH Value and Nature of a Solution
WebNo. pH + pOH is not necessarily equal to 14.000. That would only be at 25C. This is what you want to remember: pH + pOH = pKw. pKw, (and Kw) vary with temperature as do all equilibria constants. pH and Kw for a neutral solution at different temperatures T .........pH .........
