WebpKa. pK a is defined as the negative log 10 of the dissociation constant of an acid, its K a.Therefore, the pK a is a quantitative measure of how easily or how readily the acid gives up its proton [H +] in solution and thus a measure of the "strength" of the acid.Strong acids have a small pKa, weak acids have a larger pKa. The most common acid we will talk … 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.
