WebIn addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid. 3. pKa and Buffer Capacity Another important point is the relationship between pH and the pKa of an acid. This relationship is described by the following equation. WebThe acid–base strength of a molecule depends strongly on its structure. The weaker the A–H or B–H+ bond, the more likely it is to dissociate to form an H + ion. In addition, any factor that stabilizes the lone pair on the conjugate base favors the dissociation of H +, making the conjugate acid a stronger acid.

WebSep 5, 2024 · Smaller values of pKa correspond to larger acid ionization constants and hence stronger acids. Conversely, smaller values of pKb correspond to larger base ionization constants and hence stronger bases. At 25°C, pKa+pKb=14.00. What Ka value is a strong acid?
