4.13 Just as pH is the negative logarithm of [H3O+], pKa is the negative logarithm of Ka, pKa=−logKa The Henderson-Hasselbalch equation is used to calculate the pH of buffer solutions: pH=pKa+log[base][acid] Notice that the pH of a buffer has a value close to the pKa of the acid, differing only by the logarithm of the concentration ratio [base]/[acid].

NA Review | Constants 1 Periodic Table pH is a logarithmic scale used to indicate the hydrogen ion concentration, [H+], of a solution: The temperature for each solution is carried out at approximately 297 K where Kw = 1.00 x 10-14. pH = -log[H+] Due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, [OH-], are related to each other by the Kw of water: Part A Kw = [H+][OH-] =...
