WebThe table lists the K a values and the strength of each acid and base. Strong acids are listed at the top left-hand corner of the table and have Ka values >1 Acids with a K a value less than one are considered weak and get weaker as we move to the bottom of the table. WebA base ionization constant (Kb) is the equilibrium constant for the ionization of a base. pKb can be calculated by pKb = -log 10 (Kb). A large Kb value indicates the high level of dissociation of a strong base. A lower pKb value indicates a stronger base. WebThe basic dissociation constant is Kb.
