Ka vs. pKa: The Ka value for an acid is the equilibrium constant for the dissociation of the acid. While greater Ka values are associated with more potent acids, the reverse is true concerning pKa. Acid strength is commensurate to the reciprocal of the pKa value with which it is associated. Stronger acids possess smaller pKa values.Acid dissociation constant according to the Brønsted-Lowry theory. Acid dissociation constant K a (usually expressed as its negative logarithm pK a) is an equilibrium constant that shows how strong an acid HA is in the solvent S [1]: (1) HA + S ⇆ K a A-+ S H + (2) p K a =-log a (S H +) · a (A-) a (HA). In the Eq. (2), the activity of solvent S is assumed to be constant and is omitted.This problem has been solved!
