• Strong acid
• Weak acid
• Strong base
• Weak base
• Equilibrium position of acid-base reaction

Acid/Base Dissociation Constants

• Acid-ionization constant, $K_a$
• Base-ionization constant, $K_b$
• Relationship among $K_a$, $K_b$, and $K_w$
• Percent dissociation
• Monoprotic acids
• Polyprotic acids

• Strong acids and strong bases ionize almost completely in water
  • Weak acids/bases partially ionize in water
• An acid-base equilibrium reaction shifts in the direction in which a stronger acid and a stronger base form a weaker acid and weaker base
• The acid-dissociation constant, or acid-ionization constant, $K_a$ is used for acid base reactions
• Percent dissociation of a weak acid is the fraction of acid molecules that ionises at equilbrium compared with the intiial concentration of the acid
