Acids and Bases.

Weak Acids A weak acid does not ionize completely to form hydrogen ions. e.g.HC 2 H 3 O 2 (aq ) H + (aq) + C 2 H 3 O 2 - (aq) 1.3% K a = [H + (aq) ] [H.

Distinguishing Between Strong and Weak Acids and Bases Due to their greater ionization in solution, strong acids and strong bases will contain a higher concentration of ions than weak acids and weak bases. This can be used as a means of distinguishing between them. Comparisons, however, will only be valid when the solutions compared have the same concentration and are at the same temperature.
