Determining Ionic StrengthUnlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways includingKa or Kb,pKa or pKb,and percent ionization.Part APyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows:C5H5N+H2O?C5H5NH++OH?The pKb of pyridine is 8.75....
