The rest of the acids are considered weak acids and are also weak electrolytes. The hydroxides of Groups I and II are considered strong bases and are also strong electrolytes. The rest of the bases are considered as weak bases and are weak electrolytes. Most other ionic compounds are strong electrolytes. An example is PbI 2 .
Most organic compounds are nonelectrolytes.
Exceptions are organic acids and bases. The difference between strong and weak electrolytes is the extent to which the ionic compounds dissociate into ions when placed in water. The greater the amount of dissociation, the greater the electrical conductance of the solution. Ionic Bond bond formed between oppositely charged ions because of electrostatic forces of attraction. Metal atoms lose electrons to form positive ions, called cations , which are smaller than the original atom.
