is true of solutions in other non-aqueous solvents. In Table XXIV 18 

 are given values of the mass-action constants for sodium iodide in a num- 

 ber of different solvents. In Figure 6 are plotted values of the reciprocal 

 conductance against those of the specific conductance for these solutions.

FIG. 6. Showing how Solutions of Binary Electrolytes in Different Solvents Approach 

 the Mass-Action Relation at Low Concentrations. 



An examination of the figure shows that in all cases the conductance 

 curves approach a linear relation in the more dilute solutions. We may 

 conclude, therefore, that in the case of non-aqueous solvents, in general, 

 the mass-action law is approached as a limiting form at low concentra- 

 tions.
