The acid dissociation constant (Ka) is a measure of the strength of an acid in solution. It is defined as the ratio of the concentration of the dissociated form of the acid (H+) to the undissociated form (HA) at equilibrium. Mathematically, it is expressed as Ka = [H+][A-] / [HA], where [H+] is the concentration of hydrogen ions, [A-] is the concentration of the conjugate base, and [HA] is the concentration of the undissociated acid.

The acid dissociation constant (Ka) for a weak acid (HX) at equilibrium is defined by the equation: ( Ka = \frac{[H^+][X^-]}{[HX]} ). Here, ([H^+]) and ([X^-]) are the concentrations of the hydrogen ions and the conjugate base at equilibrium, respectively, while ([HX]) is the concentration of the undissociated acid. A higher Ka value indicates a stronger acid, as it signifies a greater tendency to dissociate into its ions.
