Document Summary
Recall that the strength of an electrolyte is determined by the extent of its dissociation into component ions in solution. A strong electrolyte completely dissociates into ions in solution whereas a weak electrolyte only partially dissociates, strong and weak acids are defined accordingly. A strong acid completely ionizes in solution whereas a weak acid only partially ionizes. In any case, here are some of the strongest acids: Nitric acid (hno3) sulfuric acid (h2so4) chloric acid (hclo3) perchloric acid (hclo4) Hydrochloric acid (hcl) hydrobromic acid (hbr) hydroiodic acid (hi) By analogy, a strong base is a base that completely dissociates in solution. The extent then, of the ionization of a base can be quantified with the base ionization constant, kb. Some of the strongest bases worth noting are: Sodium hydroxide (naoh) -> lye potassium hydroxide (koh) barium hydroxide [ba(oh)2] Binary acids are composed of hydrogen and a nonmetal and, in nomenclature, take the form:
