WebThere is a formula linking the values of pH and pOH which allows determining the pH or pOH based on one another. It is derived from the expression of water ionization, Kw = [H +][OH … WebpH = - log [H 3 O +] Similarly, pOH is the negative of the logarithm of the OH - ion concentration. pOH = - log [OH -] pH + pOH = 14 The equation above can be used to convert from pH to pOH, or vice versa, for any aqueous solution at 25C, regardless of how much acid or base has been added to the solution.
