CONDUCTIVITY AND VISCOSITY IN MIXED SOLVENTS. 



in other words, that there is a comparatively small increase in conductivity 

 with increase in dilution in these mixtures. It is further to be observed that 

 the conductivity values in ethyl alcohol are very much smaller than those in 

 water, although the general increase in conductivity with increase in dilution 

 is about the same in both cases. 



The temperature coefficients of conductivity in every case increase with
