An Obsolete Classification Strong and Weak Electrolytes

The classification into trae and potential electrolytes is a modem one. It is based on a knowledge of the structure of the electrolyte whether in the pure form it consists of an ionic lattice (true electrolytes) or neutral molecules (potential electrolytes) (Fig. 3.2). It is not based on the behavior of the solute in any particular solvent. 

Historically, however, the classification of electrolytes was made on the basis of their behavior in one particular solvent, i.e water. Weak electrolytes were those that yielded relatively poorly conducting solutions when dissolved in water, and strong electrolytes were those that gave highly conducting solutions when dissolved in water.
