WebNov 11, 2024 · pKa Definition. pK a is the negative base-10 logarithm of the acid dissociation constant (K a) of a solution. pKa = -log 10 K a. The lower the pKa value, the stronger the acid. For example, the pKa of acetic acid is 4.8, while the pKa of lactic acid is 3.8. Using the pKa values, one can see lactic acid is a stronger acid than acetic acid.
