WebMar 23, 2024 · The pH is thus –log (0.100) = 1.000. The formula for pH is pH = -log [H+]. This means pH is the negative base 10 logarithm (“log” on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of the hydrogen ion concentration and reverse the sign to get the answer. WebMay 1, 2024 · In a final volume of 210 ml (0.210 L), you can calculate final concentrations: [Ac-] = 0.008/0.210 = 0.038 M [HAc] = 0.012/0.210 = 0.057 M You can then use the HH equation as you did, substituting these concentrations. Do similar calculation for addition of NaOH where HAc will decrease and Ac- will increase.
