WebpKa 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. WebA lower pKa value denotes a more potent acid. That example, a lower number implies that the acid dissociates more completely in water. The pKa and pKb values are used to …

WebA lower pKa means the Ka value is higher and a higher Ka value means the acid dissociates more readily because it has a larger concentration of Hydronium ions (H3O+). Why does smaller pKa mean more acidic? More precisely – pKa is the negative log base ten of the Ka value (acid dissociation constant).

WebBecause it is the negative log (base 10) of the Ka, the lower the pKa, the stronger the acid. Also, as derived from the Henderson-Hasselbalch equation, when the pH is equal to an acid's pKa, the acid is 50% deprotonated and the concentrations of the acid and it's conjugate base are equal.
