largely dependent upon the formation of solvates between the electrolyte 

 and one or the other of the solvent components, the ionization of the 

 salt in the mixture, rather than the fluidity of the mixture, will determine 

 the form of the conductance curve and this will be the more true, the 

 more nearly the fluidity curves are linear functions of the composition.

 methyl with ethyl alcohol. 16 The data from which the curves are drawn 

 are given in Table LXXVI. 



Comparing the conductance curves with the fluidity curves, it is clear 

 that in these solutions of tetraethylammonium iodide there is a close 

 correspondence between the two. The conductance curves for mixtures 

 of methyl alcohol, ethyl alcohol and nitrobenzol correspond very closely 

 with the fluidity curves. So, also, in mixtures of water with ethyl and
