WebJan 30, 2024 · pH = pKa + log ( [conjugate base]/ [weak acid]) pH = pka+log ( [A - ]/ [HA]) pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid. At … 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. cummins isx oil thermostat delete
