In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted K a {\displaystyle K_{a}} ) is a quantitative...

a dissociation constant (KD) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly...

accurately, degree of dissociation refers to the amount of solute dissociated into ions or radicals per mole. In case of very strong acids and bases, degree...

following two acid dissociation reactions HA ⇌ H+ + A−  Ka,A = [A−][H+]/[HA] BH+ ⇌ B + H+  Ka,B = [B][H+]/[BH+] with the dissociation constants Ka,A and Ka...
