WebAug 29, 2014 · Using the properties of logarithms, Equation 2.2.8 can be rewritten as. 10 − pKw = 10 − 14. The equation also shows that each increasing unit on the scale decreases by the factor of ten on the concentration of H +. Combining Equations 2.2.4 - 2.2.6 and 2.2.8 results in this important relationship: pKw = pH + pOH = 14. dr axe top rated tumeric pills https://byfordandveronique.com
