WebOct 25, 2024 · Ka ()—the acid dissociation constant—tells you the strength of an acid in a different and more specific way than the better-known pH.Because Ka produces extremely wide-ranging values, pKa ()—the negative logarithm (base 10) of Ka—is often used to simplify the range of acid strength values.If all of this is twisting your brain a little, here’s … 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.
