MAXIMUM SPECIFIC ELECTRICAL CONDUCTIVITY IN CHEMISTRY. A) 
When, as in Fig. IIL. the conductivities of the solution of the pure electrolyte are 
plotted instead of the conductivities of the actual solution (in this case sulphuric acid 
and sugar), then the influence of the presence of the non-electrolyte molecules shows 
itself by a distortion of the graph, such that it cuts the time axis. The greater the 
concentration of the non-electrolyte, the greater the distortion, and the greater will

be the inclination of the graph towards the time axis. In Fig. III. two graphs for 
solutions of sulphuric acid containing respectively : 
(A) 1 gram cane-sugar per 50 c.c. of solution, 
(B) 0°3 gram cane-sugar per 50 c.c. of solution, 
are given. The graphs show clearly the effect of an increase in the concentration of 
the non-electrolyte. 
In A the proportion of cane-sugar is sufficient to cause a marked distortion of the 
| graph. 
In B the distortion is much less, as the conductivities are comparatively little 
different from those of pure solutions of sulphuric acid.
