Strong Acid Weak Acids Ionize completely in water (HCl, HNO 3 , HClO 4 , H 2 SO 4 ) Have weak conjugate base Partially Ionize in water (NH 4 + , HF, CH 3 COOH) At equilibrium, aq solutions of weak acids contain a mixture of nonionized acid molecules, H 3 O + ions and the conjugate base. Have strong conjugate base Strong Base Weak Base Strong electrolyte that ionize completely in water (alkaline metal and certain alkaline earth metals) Weak electrolyte.
