ACTIVITY COEFFICIENTS OF WEAK ELECTROLYTES AND

Activity Coefficients of Weak Electrolytes and Molecular Species 

In Chapters IV and V considerable effort was spent describing strong electrolytes and alternative formulations for their corresponding mean and/or ionic activity coefficients. A strict definition of a strong electrolyte is a species which completely dissociates in water. In reality, very few species fit this definition of strong electrolytes. The following definitions are offered in order to provide a practical classification of electrolytes  

Strong electrolyte - A compound which nearly completely dissociates to its 

A compound which forms non-trival quantities of non-maximally charged complexes when placed in aqueous solution. These Intermediates may be molecular or ionic. 

A compound which forms a non-trivial quantity of a molecular species when placed in aqueous solution. By this definition, weak electrolytes form a subset of complexing dectrolytes.
