For the determination of the ionisation coefficients and the numbers 

 of gramme-equivalents of the nine electrolytes in a solution of this com- 

 plexity, we have, therefore, the following equations : 



(a) from the conditions of equilibrium, 



(/>) froin the volume relation, 



X, Fi + No Fo -f . . . . + iY, T; = r . . . . 1 equation, 

 (r) from the ivlation of ionisation to dilution, 





etc., 



(<Z) from the conservation of mass, 



),, = N,-\- N,-\- N,, \ 

 n, = N, + N, + iV;, 



r,, = N2 + N, + iv;, 



n, = N, + N, + W„ 



//„ = K. + K + iV,„ 

 /(, = N, + N, + N^, 



9 equations, 



5 equati(ms, 



since each of these la.st equations maybe deduced from the other five. 

 We have thus in all twenty-seven equations for the determination' of 

 nine a's, nine JV'n, and nine F's. 



The solution of these equations by the aid of the graphical process 

 referred to above would, of course, be ideally possible ; but it M'-ould 

 probably be found impossible, with the data as to the conductivity of 

 simple solutions at jtresentat our disposal, to draw the requisite curves, 

 showing the relation of concentration of ions to dilution, with sufficient 

 accuracy for the purpose.
