CALCIUM NITRATE. 



103 



Tables 58 to 60 (figs. 38 and 39) , for calcium nitrate in mixtures of acetone 

 and water, show a point of inflection at low temperatures and high dilution. 

 In concentrated solutions, at high temperatures, the conductivity is what 

 we should expect from the law of averages. These results are similar to those 

 obtained with lithium nitrate in mixtures of acetone and water.

FIG. 39. CONDUCTIVITY OF CALCIUM NITRATE IN MIXTURES 

 OF ACETONE AND WATBR AT 25. 



The temperature coefficients of conductivity of water increase with the 

 dilution, while the temperature coefficients of acetone decrease with the 

 dilution. In the 75 per cent mixture the temperature coefficients are nearly 

 independent of the dilution. 



VISCOSITY MEASUREMENTS. 



In the table of viscosity data (table 61), the values of Thorpe and Rodger * 

 for pure water, at and 25, are taken as the standard, and the other values 

 are referred to them; 17 represents viscosity, < fluidity, and D the density 

 of the liquid in question, at s0 and 25 i , compared with the density of water 

 at and 25, respectively.
