Studies on Solution. 



term V in the tables represents the number of liters containing a gram- 

 molecular weight of the solute. K expresses the specific conductivity 

 of the solvent. 



The viscosity data were calculated from the formula rj = K- d- t-, 

 where 77 presents the viscosity coefficient, k the constant of the instru- 

 ment determined by calibration with a number of liquids of known vis- 

 cosity, d the density of the solution at the temperature in question, 

 and t the time of flow of the liquid or solution under investigation 

 at that temperature. The fluidity <p is the reciprocal of the viscos- 

 ity. The temperature coefficients represent the percentage increase 

 in fluidity between the different temperatures studied i. e., 15 to 

 25 and 25 to 35.
