WebDetermining pK a values from titration curves or free energy calculations From the titration of protonatable group, one can read the so-called p K a 1 ⁄ 2 which is equal to … WebOut of our three weak acids, hydrofluoric acid is the strongest, so it has the largest value for Ka, but notice it has the smallest value for the pKa. The lower the value for pKa, the more acidic your acid. 3.46 is lower than 4.74, and so hydrofluoric acid is more acidic than acetic acid. Up next: video.
WebpH Titration of a Weak Acid Introduction: The purpose of this lab was to construct a pH titration curve for a weak acid and from it determine the molar mass and pKa values of the acid. This was accomplished by titrating an acid, then collecting the pH of our acid every 1.0 ml and .20 ml when within 2.0 ml of our expected ha;lf neutralization, and full neutralization. WebYou should use a scatter plot in Excel and hand-draw the titration curve. Staple your Excel graphs to the report sheet. your labor Nard 2. (4) Determine the value of pK, for each acid from the titration curves. On your two titration curves, draw lines to indicate your logic and point out locations of interest.

WebDec 19, 2024 · 1 Answer. Sorted by: 2. The reason is that strong acids have p K a values that are poorly known. These p K a s cannot be determined directly, because the exact concentration of the ions is difficult to know with precision: the electrodes do not react with the concentration of H X + or H X 3 O X + ions.
